Electrical control of orbital and vibrational interlayer coupling in bi- and trilayer 2HMoS2

J. Klein, J. Wierzbowski, P. Soubelet, T. Brumme, L. Maschio, A. Kuc, K. Müller, A. V. Stier, and J. J. Finley

Phys. Rev. Materials 6, 024002 (2022) - Published 7 February, 2022

Understanding and controlling interlayer hybridization in layered van der Waals materials is an important prerequisite for developing efficient and highly tunable spin- and valleytronic devices.Here, the authors spectroscopically investigate the vibrational and orbital coupling between layers for the intricate case of bilayer and trilayer MoS2. The application of an external electric field manifests itself in field-activated phonon modes along with strongly tunable circular dichroism in both bilayer and trilayer MoS2. First-principles calculations in combination with rate equation modeling suggest that interlayer charge transfer via the Q point dominates the electron population reflected in the tunable circular dichroism. This work contributes to the understanding of the complex interplay between crystal symmetry and interlayer charge transfer in van der Waals materials.

Predicting magnetic anisotropy energies using site-specific spin-orbit coupling energies and machine learning: Application to iron-cobalt nitrides

Timothy Liao, Weiyi Xia, Masahiro Sakurai, Renhai Wang, Chao Zhang, Huaijun Sun, Kai-Ming Ho, Cai-Zhuang Wang, and James R. Chelikowsky

Phys. Rev. Materials 6, 024402 (2022) - Published 7 February, 2022

The authors present a promising machine learning model, which focuses on site-magnetic-properties for rapid screening in materials design and accelerates computational screening of candidate materials that possess high magnetizations and large magnetic anisotropy energies.

Spatial extent of the Dzyaloshinskii-Moriya interaction at metallic interfaces

William Legrand, Yanis Sassi, Fernando Ajejas, Sophie Collin, Laura Bocher, Hongying Jia, Markus Hoffmann, Bernd Zimmermann, Stefan Blügel, Nicolas Reyren, Vincent Cros, and André Thiaville

Phys. Rev. Materials 6, 024408 (2022) - Published 23 February, 2022

Inversion-asymmetric stacks of metallic magnetic layers have often been exploited to control the chiral noncollinear ordering of their magnetic moments. Here, the authors investigate the interfacial aspects of the Dzyaloshinskii-Moriya interaction, giving rise to this chiral magnetic ordering, and quantify its contributions to within a couple atomic layers. This observation is further supported by first-principles calculations. The confirmation of the short spatial extent of the interfacial DMI is expected to enable the synthesis of dense magnetic multilayers and to offer further possibilities for engineering their spintronic properties.
