Robust Exchange Bias in van der Waals Heterostructures of Topological Insulators and Metallic Ferromagnets

Wuyi Qi, Zheng Dai, Heng Zhang, Tianqi Wang et autres

Abstract Exchange bias from ferromagnet (FM) and antiferromagnet (AFM) interface underpins modern spintronics and magnetic technologies. Van der Waals (vdW) magnets allow arbitrary stacking, offering richer material and device choices. However, challenges arise when integrating FM metals with vdW topological materials. Conductive …

Exchange operation of Majorana zero modes in topological insulator-based Josephson trijunctions

Yunxiao Zhang, Zhaozheng Lyu, Xiang Wang, Yukun Shi et autres

Majorana zero modes are anyons obeying non-Abelian exchange statistics distinct from fermions or bosons. While significant progresses have been achieved in the past two decades in searching for these exotic excitations in solid-state systems, their non-Abelian nature remains unverified, as definitive proof …
