Detachment-limited interlayer transport processes during $SrTi O_{3}$ pulsed laser epitaxy

Jeffrey G. Ulbrandt, Xiaozhi Zhang, and Randall L. Headrick

Phys. Rev. Materials 9, 103405 (2025) - Published 29 October, 2025

Understanding atomistic transport mechanisms during pulsed laser deposition (PLD) remains a central challenge for the synthesis of complex oxide thin films. This study combines time-resolved X-ray scattering and kinetic Monte Carlo simulations to reveal the dynamics of a two-stage relaxation process following each laser pulse. Fast nonthermal transport is followed by slower detachment-limited ripening of transient islands, showing how local coordination-dependent energy barriers govern interlayer mass transport. These findings provide new insight into PLD growth dynamics and demonstrate how the specular and diffuse scattering captures both vertical and lateral surface evolution on submonolayer length and time scales.

Accelerating the development of oxynitride thin films: A combinatorial investigation of the Al-Si-O-N system

Stefanie Frick, Oleksandr Pshyk, Arnold Müller, Alexander Wieczorek, Kerstin Thorwarth, and Sebastian Siol

Phys. Rev. Materials 9, 103803 (2025) - Published 24 October, 2025

The material class of oxynitrides shows remarkable versatility due to the substantial tuneability of their functional properties via the O/N-ratio. To accelerate oxynitride coating development, three different approaches are investigated in this study targeting the fabrication of orthogonal anion and cation gradients on a single substrate using combinatorial magnetron sputtering. To demonstrate the potential of the most effective approach, a proof-of-concept study on the quaternary Al-Si-O-N system was conducted, performing a comprehensive screening of mechanical and optical properties relevant for protective anti-reflection coatings.

Linking acoustic emission signals to deformation mechanisms in magnesium

Shimon Bettan, Emil Bronstein, Hanus Seiner, Petr Sedlak, Martin Koller, Doron Shilo, and Eilon Faran

Phys. Rev. Materials 9, 103805 (2025) - Published 31 October, 2025

Understanding a material’s behavior requires insight into how microscopic deformation mechanisms evolve, but identifying these processes at the level of individual microscopic events is a major challenge. Here, the authors present a physics-guided, data-driven spectral analysis of acoustic emission (AE) signals to classify individual deformation events in a magnesium single crystal. The analysis links AE frequency signatures to twinning and slip mechanisms and validates them through resonance ultrasound spectroscopy and modal calculations. Thus, the study achieves unsupervised classification of deformation events, uncovering the transition from twinning-dominant to slip-dominant behavior. This approach offers a new pathway for mechanism-specific monitoring of damage evolution.

Determining exciton binding energy and reduced effective mass in metal tri-halide perovskites from optical and impedance spectroscopy measurements

K. Lizárraga, J. A. Guerra, L. A. Enrique-Moran, E. Serquen, E. Ventura, Cesar E. P. Villegas, A. R. Rocha, and P. Venezuela

Phys. Rev. Materials 9, 103806 (2025) - Published 31 October, 2025

This work presents a new method to accurately determine exciton binding energy and reduced effective mass in bulk halide perovskites by accounting for polarization effects from carrier-phonon interactions. The exciton-polaron binding energy is estimated using optical absorption measurements and the Elliott-based Band Fluctuations (EBF) model. The reduced effective mass is then derived by combining the results from the EBF model with the Pollmann-Buettner exciton-polaron theory, which incorporates electron-phonon coupling by leaving in consideration the ionic and electronic dielectric responses, as well as the LO phonon energy. When applied to $A B X_{3}$ perovskites ( $A$ = MA, FA, Cs; $B$ = Pb; $X$ = I, Br, Cl), this approach shows excellent agreement with magnetoabsorption and other optical-resolved methods, confirming its accuracy and broad applicability which could be extended to other polar systems.

Depth-resolved magnetic order in superconducting topological insulator/FeTe thin film heterostructures

Purnima P. Balakrishnan, Hemian Yi, Zi-Jie Yan, Wei Yuan, Andreas Suter, Christopher J. Jensen, Pascal Manuel, Fabio Orlandi, Takayasu Hanashima, Christy J. Kinane, Andrew J. Caruana, Dirk Backes, Padraic Shafer, Brian B. Maranville, Zaher Salman, Thomas Prokscha, Cui-Zu Chang, and Alexander J. Grutter

Phys. Rev. Materials 9, 104203 (2025) - Published 14 October, 2025

Despite being structurally and chemically similar to the prominent superconductor FeSe, FeTe is antiferromagnetic and non-superconducting in the bulk. While it has often been presumed that the magnetism and lack of superconductivity in this material are linked, findings relating the two yield conflicting results and are complicated by phase separation. Using a range of topologically nontrivial capping layers to stabilize interfacial FeTe superconductivity, the authors show that the suppression of the antiferromagnetic state in FeTe is unlikely to be the primary factor driving superconductivity. Instead, They find evidence that subtle changes in Fe content likely drive the transition.

Tuning magnetic ground states of ${R Mn}_{6} {Sn}_{6}$ ( $R$ = Lu, Mg) kagome metals by dimensionality reduction: Route to ferromagnetism and large anomalous Hall effect

Rajdeep Biswas, Jyoti Sharma, Aftab Alam, and Tanusri Saha Dasgupta

Phys. Rev. Materials 9, 104205 (2025) - Published 30 October, 2025

By employing computational methods, the authors have demonstrated that dimensionality reduction provides an effective strategy for engineering electronic and magnetic structures. Specifically, starting from the bulk Kagome parent compound RMn $_{6}$ Sn $_{6}$ (R = Lu, Mg), this approach has led to the design of ferromagnetic thin films RMn $_{6}$ Sn $_{8}$ , where the RKKY interaction stabilizes robust ferromagnetism. These films exhibit Weyl states, nontrivial band crossings, large Berry curvature, and a pronounced anomalous Hall effect. As Kagome metallic Weyl ferromagnets, these 2D structures combine strong magnetism with nontrivial topology, offering pathways for spintronics, low-power memory, Hall sensors, and energy-efficient device engineering.

Magnetic polaron formation in ${EuZn}_{2} P_{2}$

Phys. Rev. Materials 9, 104403 (2025) - Published 2 October, 2025

Colossal magnetoresistance (CMR) is widely observed in Eu-based semiconductors, despite the absence of the conventional mechanisms that drive CMR in the perovskite manganites. In this work, the authors demonstrate compelling evidence for magnetic polaron formation as the origin of CMR in antiferromagnetic EuZn $_{2}$ P $_{2}$ using comprehensive analysis of electrical transport, magnetization, dilatometry, and electron spin resonance (ESR) measurements. A peak in the CMR response near the antiferromagnetic ordering temperature is accompanied by a field-induced lattice strain, while ESR analysis suggests strong ferromagnetic exchange interactions between Eu $^{2 +}$ moments and conduction electrons. The authors’ collective observations in EuZn $_{2}$ P $_{2}$ support the view that magnetic polaron formation is central to the emergence of CMR in Eu $^{2 +}$ -based compounds.

Nonequilibrium molecular dynamics of ion conduction with equivariant neural network models

Saori Minami, Alex Kutana, Ryosuke Jinnouchi, and Ryoji Asahi

Phys. Rev. Materials 9, 103802 (2025) - Published 15 October, 2025

The authors propose a machine-learning approach that integrates nonequilibrium molecular dynamics under a constant electric field with equivariant neural network models to evaluate ionic conductivity in solid electrolytes. In this approach, Born effective charges are predicted by an equivariant graph neural network and used to describe field-induced forces and current density. These forces are combined with unperturbed forces from an equivariant neural network potential. Applied to the representative solid electrolyte Li₁₀GeP₂S₁₂, the method achieves first-principles accuracy at a fraction of the computational cost. It also captures charge fluctuations in complex materials, providing new physical insights into ionic dynamics.

Decoratypes: An extensible crystal taxonomy for machine learning-guided materials discovery

Kyle D. Miller, Michele Campbell, Danilo Puggioni, and James M. Rondinelli

Phys. Rev. Materials 9, 104404 (2025) - Published 3 October, 2025

The authors present decoratypes, a new extensible crystal taxonomy that offers a more granular lens for structure–property relationships by classifying materials by hierarchical property-site mappings. For example, the framework generalizes anti-structures into polaritypes, a subclass of decoratype. They demonstrate its utility by building a polaritype-based active learning workflow for discovering ferroelectric and hyperferroelectric materials. Our approach identified six novel candidates, including three strain-activated ferroelectrics and three strain-activated hyperferroelectrics. These findings highlight how decoratypes can provide a novel perspective on the search for functional materials in underexplored chemical spaces.

Phys. Rev. Materials 9, 104802 (2025) - Published 7 October, 2025

Transverse resistance (Hall effect) offers a sensitive probe into the properties of two-dimensional superconductors. In this work, the authors systematically investigate the transverse resistance in superconducting LaAlO $_{3}$ /KTaO $_{3}$ (111) interfaces and observe two distinct anomalies: a sharp transverse resistance peak during zero-field cooling, and a strongly even-symmetric signal under magnetic field sweeps–markedly departing from the conventional odd-symmetric Hall behavior. These features are explained by microscopically uneven vortex distributions, reflecting intrinsic inhomogeneity and unique vortex dynamics at the oxide interface.

Phys. Rev. Materials 9, 105003 (2025) - Published 30 October, 2025

The authors report a giant topological Hall effect at room temperature in permalloy/La $_{0.65}$ Sr $_{0.35}$ MnO $_{3}$ (Py/LSMO) heterostructures, with resistivity reaching ~2.8 μΩ·cm, far exceeding that of single-layer Py. The effect arises from the interplay of LSMO ferromagnetism and Rashba spin–orbit coupling at the broken-symmetry interface. Magnetic imaging reveals the presence of skyrmion-like spin textures, which are further tunable with a ferroelectric spacer, as corroborated by theoretical modeling. These findings establish Py/LSMO heterostructures as a promising platform to manipulate interfacial spin textures and advance next-generation spintronic technologies.

What happens when two tiny gold spheres come so close that only a few atoms separate them? At this scale, classical physics gives way to quantum effects, but measuring such ultra-small gaps has remained notoriously difficult. Here, the authors introduce a 3D electron microscopy workflow combined with a robust fitting model to achieve sub-pixel accuracy. This strategy provides reliable morphology-optics correlations, paving the way toward resolving quantum effects in nanoscale light-matter interactions and enabling the rational design of plasmonic nanostructures.

Using a fine-tuned machine learning interatomic potential, the authors performed large-scale molecular dynamics simulations to reveal this transformation. The simulations map the atomic-level transition from a disordered structure to a partially disordered, spinel-like phase. This transformed phase features enhanced Li-ion transport pathways, and the analysis further clarifies the role of Mn valence states and correlates cation ordering with intercalation voltage profiles.
