Surface ferromagnetism in a chiral topological semimetal CoSi
N. N. Orlova, A. A. Avakyants, A. V. Timonina +2
Despite the chiral topological semimetal CoSi is known as bulk diamagnetic, it shows unusual surface ferromagnetism of debatable origin. The ferromagnetic ordering has been attribu…
Second-harmonic response as a tool to detect spin textures in magnetic nodal-line semimetal FeGeTe
V. D. Esin, A. A. Avakyants, A. V. Timonina +2
We experimentally investigate second-harmonic transverse voltage response to ac electrical current for a magnetic nodal-line semimetal FeGeTe. For zero magnetic field, the…
Evidence for surface spin structures from first order reversal curves in Co3Sn2S2 and Fe3GeTe2 magnetic topological semimetals
A. A. Avakyants, N. N. Orlova, A. V. Timonina +2
We study magnetization reversal and first order reversal curves for two different magnetic topological semimetals, Co3Sn2S2 and Fe3GeTe2, in a wide temperature range. For the magne…
Dynamic negative capacitance regime in GeTe Rashba ferroelectric
N. N. Orlova, A. V. Timonina, N. N. Kolesnikov +1
We experimentally investigate capacitance response of a thick ferroelectric GeTe single-crystal flake on the Si/SiO2 substrate, where p-doped Si layer serves as a gate electrode. W…
