Jsymm: A Python package for symmetry analysis of exchange tensors in magnetic Hamiltonians
A. S. Sergeev, S. V. Streltsov
Symmetries of a crystal often restrict its physical properties. In particular, they determine possible forms of the tensors that describe interatomic exchange interaction, which go…
Ising spin ladders of orthopyroxene CoGeO
Pavel A. Maksimov, Andrey F. Gubkin, Alexey V. Ushakov +6
We present thermodynamic and spectroscopic measurements for an orthopyroxene CoGeO with magnetic Co ions that form quasi-one-dimensional ladders. We show that non-collin…
Beyond Germanides: Anomalous Hall Effect in the Silicide LaMn2Si2
S. V. Streltsov, D. M. Korotin
By combining symmetry analysis and direct density functional calculations including the spin-orbit coupling, we demonstrate that anomalous Hall effect can be observed in not only g…
Rattling Phonon Modes in Quadruple Perovskites
Z. V. Pchelkina, E. V. Komleva, V. Yu. Irkhin +2
Rattling phonon modes are known to be origin of various anomalous physical properties such as superconductivity, suppression of thermal conductivity, enhancement of specific heat e…
Cobalt-Based Pyroxenes: A New Playground for Kitaev Physics and Ising Model Realization
Pavel A. Maksimov, Alexey V. Ushakov, Andey F. Gubkin +8
Recent advances in the study of cobaltites have unveiled their potential as a promising platform for realizing Kitaev physics in honeycomb systems and the Ising model in weakly cou…
Ground-state structure, orbital ordering and metal-insulator transition in double-perovskite PrBaMn2O6
Sergey V. Streltsov, R. E. Ryltsev, N. M. Chtchelkatchev
In recent years, A-site ordered half-doped double-perovskite manganites (R=rare earth) have attracted much attention due to their remarkable physical properties an…
