Spin-phonon interaction in a symmetry-enforced spin-polarized state
Suman Kalyan Pradhan, Dayal Das, Shubham Patel +8
Symmetry-governed magnetic materials have emerged as a promising platform for spintronic functionalities without net magnetization or stray magnetic fields, motivating the explorat…
Topological spin-texture transitions in van der Waals magnets revealed by X-ray Fourier transform holography
Sourav Chowdhury, Soumyaranjan Dash, Michael Schneider +14
Nontrivial topological spin-textures, such as skyrmions, merons, bimerons, and skyrmioniums, are envisioned as robust building blocks for future memory and logic devices. Controlla…
Low magnetic moment and unconventional magneto-transport in half-Heusler alloy CoVGe
Ravinder Kumar, Jyotiraditya Pandey, Shoaib Akhtar +4
In the present work, we experimentally realize CoVGe for the first time and investigate its structural, magnetic, and transport properties, supported by theoretical calculations. T…
Magnetic field-induced non-trivial Lifshitz transition in TaCo2Te2
Suman Kalyan Pradhan, Xiaoming Ma, Jicheng Wang +14
Magnetic-field-driven Lifshitz transitions are typically considered zero-temperature phenomena involving Fermi-surface reconstruction without symmetry breaking. Here, we report an…
Unraveling effects of competing interactions and frustration in vdW ferromagnetic Fe3GeTe2 nanoflake devices
Rajeswari Roy Chowdhury, Daiichi Kurebayashi, Jana Lustikova +4
Two-dimensional (2D) van der Waals (vdW) magnets and devices have garnered significant attention owing to the stabilization of long range magnetic order down to atomic limit, and t…
Giant Topological Hall Effect in Magnetic Weyl Metal MnPdIrSn
Arnab Bhattacharya, Afsar Ahmed, Sreeparvathy PC +6
The synergy between real and reciprocal space topology is anticipated to yield a diverse array of topological properties in quantum materials. We address this pursuit by achieving…
