Highly tunable topological system based on PbTe-SnTe binary alloy

Cheng-Long Zhang, Tian Liang, Naoki Ogawa, Yoshio Kaneko, Markus Kriener, Taro Nakajima, Yasujiro Taguchi, and Yoshinori Tokura

Phys. Rev. Materials 4, 091201(R) (2020) - Published 22 September, 2020

Despite lots of research activities on topological materials, a highly tunable system is yet to be realized as a material platform for exploration of versatile magneto-/opto-/thermoelectronic properties. The authors followed an important scheme for topological phase transitions proposed by S. Murakami et al. and could find a highly tunable topological system based on PbTe-SnTe alloy doped with In. By varying parameters, Pb/Sn ratio and In doping, they can tune the system from trivial to topological-crystalline insulators across a finite range of materials, where the system shows polar distortion and topological semi-metal behaviors with low-carrier density, high mobility and anomalous (in-plane as well as out-of-plane field) Hall effects.

Giant anisotropic magnetoresistance in oxygen-vacancy-ordered epitaxial ${La}_{0.5} {Sr}_{0.5} Co O_{3 - δ}$ films

Jeff Walter, Shameek Bose, Mariona Cabero, Maria Varela, and Chris Leighton

Phys. Rev. Materials 4, 091401(R) (2020) - Published 17 September, 2020

Anisotropic Magnetoresistance (AMR) is a property of all conductive ferromagnets, where the electrical resistivity depends on the relative orientation of the current and magnetization. In this work it is shown that the perovskite cobaltite La1-xSrxCoO3-d displays a giant form of AMR in epitaxial thin films, 20 times enhanced over bulk, and 10-100 times typical transition metals. The effect is ascribed to symmetry lowering due to spatial ordering of oxygen vacancies, pointing to a new route to enhance properties of complex oxides. The AMR values (up to 40%) are among the largest reported in the 160-year history of the effect.

Discovery of highly polarizable semiconductors $BaZr S_{3}$ and ${Ba}_{3} {Zr}_{2} S_{7}$

Stephen Filippone, Boyang Zhao, Shanyuan Niu, Nathan Z. Koocher, Daniel Silevitch, Ignasi Fina, James M. Rondinelli, Jayakanth Ravichandran, and R. Jaramillo

Phys. Rev. Materials 4, 091601(R) (2020) - Published 8 September, 2020

Few semiconductors exhibit both strong optical response and large dielectric polarizability without an accompanying phase transition. In this paper, the authors introduce complex chalcogenides in the Ba-Zr-S system with perovskite and Ruddlesden-Popper structures as a new family of highly polarizable semiconductors, with low-frequency dielectric constant exceeding the highest reported values for semiconductors with band gap in the NIR-VIS, including halide perovskites. This family of complex chalcogenide semiconductors therefore combines strong optical absorption, excellent environmental stability, and strong dielectric response, and consists of abundant and nontoxic elements. It is an open question whether the strong dielectric polarizability reported here is related to the slow rates of nonradiative energy loss reported previously in Ba $_{3}$ Zr $_{2}$ S $_{7}$ .

From latent ferroelectricity to hyperferroelectricity in alkali lead halide perovskites

Guido Roma, Arthur Marronnier, and Jacky Even

Phys. Rev. Materials 4, 092402(R) (2020) - Published 11 September, 2020

Since the blooming of research on hybrid halide perovskites, ferroelectricity was suspected to play a role in their outstanding photovoltaic properties, but its evidence is still debated. Here, the authors show, using first principles calculations, that a whole family of inorganic lead halide perovskites exhibits at least latent ferroelectric behavior and, for some less explored compounds, even hyperferroelectricity. For this robust form of ferroelectricity, the polarization shows hysteresis not only versus the electric field, but also versus the electric displacement; in other words, the spontaneous polarization survives despite depolarization fields arising from surface charges. Implications are expected also for optoelectronic and spinorbitronic applications and 2D perovskites.

Theory of tunable flux lattices in the homobilayer moiré of twisted and uniformly strained transition metal dichalcogenides

Dawei Zhai and Wang Yao

Phys. Rev. Materials 4, 094002 (2020) - Published 1 September, 2020

This work studies moiré structures formed in homobilayer transition metal dichalcogenides (TMDs) due to twisting and/or uniform strain, where the layer index serves as a pseudospin. The layer pseudospin exhibits vortex/antivortex textures in the moiré supercell. Such spatial texture gives rise to a pseudomagnetic field and a geometric scalar potential on low energy electrons. Strain and interlayer bias are shown to tune the in-plane and out-of-plane pseudospin texture, hence, the landscape of the moiré magnetic field and scalar potential. The findings suggest that TMD moiré structures are promising to build tunable ﬂux lattices for exploration of novel transport and topological phenomena.

Strain and electric-field control of spin-spin interactions in monolayer ${CrI}_{3}$

Sahar Izadi Vishkayi, Zahra Torbatian, Alireza Qaiumzadeh, and Reza Asgari

Phys. Rev. Materials 4, 094004 (2020) - Published 18 September, 2020

Controlling the magnetic and electronic properties of 2D materials is important for their promising applications in low-dimensional spintronics. In this paper, the authors are focused on the control and manipulation of spin-spin interactions in monolayer CrI $_{3}$ by applying strain and electric fields. A suitable spin model Hamiltonian is used to compute the isotropic and anisotropic symmetric exchange interactions, Dzyaloshinskii-Moriya interactions, and anisotropy energy of monolayer CrI $_{3}$ as a representative of 2D transition metal trihalides.

$L 1_{0}$ rare-earth-free permanent magnets: The effects of twinning versus dislocations in Mn-Al magnets

Yuxiao Jia, Yuye Wu, Shuang Zhao, Shulan Zuo, Konstantin P. Skokov, Oliver Gutfleisch, Chengbao Jiang, and Huibin Xu

Phys. Rev. Materials 4, 094402 (2020) - Published 10 September, 2020

Defects of various kinds play a crucial role on coercivity in rare-earth-free permanent magnetic alloys with L10 structure. In this work, the negative effect of twin structure and the positive effect of dislocations on the coercivity are clarified in a systematic experimental study of L10-MnAl alloys, because the former defect can induce the nucleation of reversal domain and the latter can act as a pinning center. Thus, the combination of eliminating twin structure and introducing high-density dislocations could overcome the present bottleneck in magnetic performance. This work may inspire avenues for the development of L10 rare-earth-free permanent magnetic alloys.

Magneto-Seebeck microscopy of domain switching in collinear antiferromagnet CuMnAs

T. Janda et al.

Phys. Rev. Materials 4, 094413 (2020) - Published 28 September, 2020

The authors introduce a novel microscopy for antiferromagnetic nanostructures based on the local generation and detection of photocurrents, and apply it to the collinear and fully compensated antiferromagnet CuMnAs. By using the optical near field generated by a scattering near-field microscope, they display narrow 180 $^{\circ}$ domain walls (DWs) and provide the first experimental evidence of reversible current-pulse-driven 180 $^{\circ}$ DW displacements in agreement with theoretically predicted Néel spin-orbit torque DW motion. In CuMnAs, photocurrents result from the local magneto-Seebeck effect (MSE). MSE-based microscopy can be applied to the entire class of conductive antiferromagnets, and in contrast to the established X-ray linear dichroism microscopy which is based on large scale synchrotrons, it can be easily performed with common laboratory equipment.

Optical properties of $Cs {Cu}_{2} X_{3}$ $(X = Cl, Br, and I)$ : A comparative study between hybrid time-dependent density-functional theory and the Bethe-Salpeter equation

Jiuyu Sun and Carsten A. Ullrich

Phys. Rev. Materials 4, 095402 (2020) - Published 17 September, 2020

CsCu $_{2}$ X $_{3}$ (X= Cl, Br, I) are quasi-one-dimensional, all-inorganic perovskites which are promising for optoelectronic applications. In this work, optical absorption spectra of CsCu $_{2}$ X $_{3}$ , with particular emphasis on excitonic features, are calculated via the Bethe-Salpeter equation (BSE) and time-dependent density-functional theory (TDDFT), in combination with the $G W$ method. It is found that hybrid TDDFT, with a material-dependent admixture of nonlocal exchange determined by the dielectric constant, produces optical spectra in excellent agreement with the BSE. This suggests that hybrid functionals are very well suited for calculating the optical properties of perovskites and other materials, at a fractional cost of standard $G W$ +BSE.
