Accurate force field of two-dimensional ferroelectrics from deep learning

Jing Wu, Liyi Bai, Jiawei Huang, Liyang Ma, Jian Liu, and Shi Liu

Phys. Rev. B 104, 174107 (2021) - Published 17 November, 2021

A force field that accurately describes interatomic interactions is the prerequisite for running molecular dynamics, an efficient method for large-scale simulations. Compared to the large number of two-dimensional (2D) materials, only a handful of force fields of 2D materials have been developed. Using a concurrent learning procedure that efficiently updates the training database, the authors develop here a deep neural-network-based force field for monolayer In2Se3. The deep potential enabled the predictions of a range of thermodynamic properties of In2Se3 polymorphs, including the ferroelectric α phase.

Eleonora Guarini, Fabrizio Barocchi, Alessio De Francesco, Ferdinando Formisano, Alessio Laloni, Ubaldo Bafile, Milva Celli, Daniele Colognesi, Renato Magli, Alessandro Cunsolo, and Martin Neumann

Phys. Rev. B 104, 174204 (2021) - Published 10 November, 2021

Quantum liquids are growing in importance both in research and applications. Some of their properties, however, are not easy to measure or simulate. By means of a comprehensive analysis of neutron Brillouin scattering on the semiquantum deuterium liquid, the authors demonstrate that experiment and current semiclassical simulation methods deliver different results for the principal manifestation of the quantum nature of cold liquids in their dynamical properties, which is the rather long lifetimes of collective excitations.

Chiral order and multiferroic domain relaxation in NaFeGe2O6

S. Biesenkamp, D. Gorkov, W. Schmidt, K. Schmalzl, Y. Sidis, P. Becker, L. Bohatý, and M. Braden

Phys. Rev. B 104, 174405 (2021) - Published 4 November, 2021

Controlling chiral magnetic domains in a multiferroic material is promising for applications in spintronics or data storage devices. The authors study the electric-field driven relaxation of multiferroic domains in NaFeGe2O6 as a function of temperature and electric field over several decades in time. An astonishingly simple combination of an Arrhenius-like temperature dependence with a Merz law for the electric-field dependence describes the relaxation times with only two parameters, indicating that multiferroic relaxation is essentially determined by domain-wall motion.

Spin resonance amplitude and frequency of a single atom on a surface in a vector magnetic field

Jinkyung Kim, Won-jun Jang, Thi Hong Bui, Deung-Jang Choi, Christoph Wolf, Fernando Delgado, Yi Chen, Denis Krylov, Soonhyeong Lee, Sangwon Yoon, Christopher P. Lutz, Andreas J. Heinrich, and Yujeong Bae

Phys. Rev. B 104, 174408 (2021) - Published 8 November, 2021

To characterize the local magnetic environment at the tunnel junction in a scanning tunneling microscope, the authors utilize as a rotatable spin sensor a spin-1/2 hydrogenated Ti atom on a surface. They measure the electron spin resonance at different Ti spin directions as controlled by two-axis magnets and clarify the crystal-field and magnetic-tip effects at the STM junction, identifying the origin of the giant (15%) anisotropy of g factors for Ti on the surface and the variable driving and readout of spin resonance.

Disentangling electronic, lattice, and spin dynamics in the chiral helimagnet Cr1/3NbS2

N. Sirica, H. Hedayat, D. Bugini, M. R. Koehler, L. Li, D. S. Parker, D. G. Mandrus, C. Dallera, E. Carpene, and N. Mannella

Phys. Rev. B 104, 174426 (2021) - Published 19 November, 2021

Measurements of the static and ultrafast magneto-optical responses in the hexagonal chiral helimagnet Cr1/3NbS2 are made above and below the helimagnetic ordering temperature to disentangle the electronic, lattice, and spin dynamics. The data are inconsistent with conventional mechanisms that explain the observed demagnetization dynamics. The interpretation of a slow demagnetization in Cr1/3NbS2 necessitates taking into account important details of the electronic structure and, in particular, the nontrivial interaction of local moments and itinerant electrons.

Emergent magnetic states due to stacking and strain in the van der Waals magnetic trilayer CrI3

Zhen Zhang, Jing-Yang You, Bo Gu, and Gang Su

Phys. Rev. B 104, 174433 (2021) - Published 23 November, 2021

To reveal the crystal structure of three observed magnetic states in trilayer CrI3, the authors investigate, by means of first-principles calculations, four stacking structures in trilayer CrI3, in which the magnetic state was found to be well tuned by stacking structure along with tensile strain. After applying some tensile strain, structure I (rhombohedral) maintains FM-↑↑↑, structures II (monoclinic) and III (hexagonal) favor FM-↓↑↓, while structure IV (triclinic) prefers FM-↑↑↓. These are good interpretations of the experimentally obtained magnetic phases.

Magnetic properties of the intercalated compound Lu2Fe3O7

Sabreen S. Hammouda, Thomas Mueller, Eugen Weschke, and Manuel Angst

Phys. Rev. B 104, 174437 (2021) - Published 24 November, 2021

Complex spin and charge order in the frustrated Fe/O bilayers of rare-earth ferrites RFe2O4 and proposed multiferroicity for R = Lu have attracted a lot of interest. The authors focus on intercalated Lu2Fe3O7, with additional Fe/O single layers inserted between the bilayers. Macroscopic magnetization measurements, polarized neutron scattering, and x-ray magnetic circular dichroism indicate that spin-charge coupling and the local spin arrangement in each individual bilayer is the same as in the nonintercalated compound, with the Fe spins in the single layers giving rise to an additional paramagneticlike contribution.

Magnetic structure determination of high-moment rare-earth-based laminates

D. Potashnikov, E. N. Caspi, A. Pesach, Q. Tao, J. Rosen, D. Sheptyakov, H. A. Evans, C. Ritter, Z. Salman, P. Bonfa, T. Ouisse, M. Barbier, O. Rivin, and A. Keren

Phys. Rev. B 104, 174440 (2021) - Published 29 November, 2021

The laminate (Mo2/3Gd1/3)2AlC, based on high-moment Gd, grows as pristine crystals and might exfoliate or be etched into two-dimensional magnets, but its properties are unknown since Gd is a strong neutron absorber. Bypassing this difficulty, the authors succeed in determining the magnetic structure by combining neutron diffraction studies on isostructural compounds with muon spin rotation studies including first-principles site calculations and, most importantly, initial muon spin polarization variations.

Reentrant superconductivity through a quantum Lifshitz transition in twisted trilayer graphene

Ethan Lake and T. Senthil

Phys. Rev. B 104, 174505 (2021) - Published 8 November, 2021

Twisted trilayer graphene has recently been demonstrated to host a robust superconducting phase, with experiments demonstrating a “reentrant” phenomenon: large magnetic fields destroy superconductivity, but still larger fields bring it back to life. In this work, the authors use simple insights from theory and experiment to provide an understanding of this phenomenon, along the way arguing that the superconductor is likely to involve a superposition of both singlet and triplet pairing. Many of the conclusions of this study can also be applied to twisted bilayer graphene, and forthcoming experiments should allow these conclusions to be put to the test.

Microwave response of an Andreev bound state

Pavel D. Kurilovich, Vladislav D. Kurilovich, Valla Fatemi, Michel H. Devoret, and Leonid I. Glazman

Phys. Rev. B 104, 174517 (2021) - Published 23 November, 2021

The simplest junction between two superconductors hosts one Andreev bound state, which can be occupied by 0, 1, or 2 quasiparticles. The properties of these many-body states are sensitive to the spatial structure of single-particle wave functions as well as to charging effects. These influences are revealed through the microwave response of the junction.

Complex spin and charge order in the frustrated Fe/O bilayers of rare-earth ferrites RFe2O4 and proposed multiferroicity for R = Lu have attracted a lot of interest. The authors focus on intercalated Lu2Fe3O7, with additional Fe/O single layers inserted between the bilayers. Macroscopic magnetization measurements, polarized neutron scattering, and x-ray magnetic circular dichroism indicate that spin-charge coupling and the local spin arrangement in each individual bilayer is the same as in the nonintercalated compound, with the Fe spins in the single layers giving rise to an additional paramagneticlike contribution.

The laminate (Mo2/3Gd1/3)2AlC, based on high-moment Gd, grows as pristine crystals and might exfoliate or be etched into two-dimensional magnets, but its properties are unknown since Gd is a strong neutron absorber. Bypassing this difficulty, the authors succeed in determining the magnetic structure by combining neutron diffraction studies on isostructural compounds with muon spin rotation studies including first-principles site calculations and, most importantly, initial muon spin polarization variations.

Reentrant superconductivity through a quantum Lifshitz transition in twisted trilayer graphene

Phys. Rev. B 104, 174505 (2021) - Published 8 November, 2021

Twisted trilayer graphene has recently been demonstrated to host a robust superconducting phase, with experiments demonstrating a “reentrant” phenomenon: large magnetic fields destroy superconductivity, but still larger fields bring it back to life. In this work, the authors use simple insights from theory and experiment to provide an understanding of this phenomenon, along the way arguing that the superconductor is likely to involve a superposition of both singlet and triplet pairing. Many of the conclusions of this study can also be applied to twisted bilayer graphene, and forthcoming experiments should allow these conclusions to be put to the test.

The simplest junction between two superconductors hosts one Andreev bound state, which can be occupied by 0, 1, or 2 quasiparticles. The properties of these many-body states are sensitive to the spatial structure of single-particle wave functions as well as to charging effects. These influences are revealed through the microwave response of the junction.
