The re-entrant ferromagnetism due to symmetric exchange bias in two septuple-layer MnBi2Te4 epitaxial films
Dezhi Song, Fuyang Huang, Gang Yao +10
MnBi2Te4 (MBT) is a typical magnetic topological insulator with an A-type antiferromagnetic (AFM) ground state. Here we prepared ultra-thin MBT films with controlled anti-site defe…

The spin-switch scanning tunneling microscopy: an architecture to probe electron-phonon interactions in the atomic scale
Dezhi Song, Fuyang Huang, Yu Gao +7
On the spin-valve-like ferromagnet/spin glass/ferromagnet (FM/SG/FM) structure, the tunneling current is dominated by resistance switch (RS) instead of the local density of states…

Resistance switch in ferromagnet/spin glass/ferromagnet spin valves
Dezhi Song, Fuyang Huang, Gang Yao +7
We obtain in single van-der-Waals layer of MnBi2Te4 the spin-valve-like ferromagnet/spin glass (SG)/ferromagnet architecture, where the switch of individual spin states in the SG-l…
