Tunable thermal conductivity through dual spin-phonon coupling in van der Waals ferromagnetic insulator Cr2Ge2Te6
Zhongbin Wang, Wenlong Tang, Simin Pang +8
The active manipulation of phonon transport remains a central challenge in phononics and spin caloritronics due to the charge-neutral nature of heat carriers. Spin-phonon coupling…
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…
The experimental determination of exchange mass terms in surface states on both terminations of MnBi4Te7
Dezhi Song, Fuyang Hang, Gang Yao +3
The intrinsic antiferromagnetic topological insulators in the Mn-Bi-Te family, composed of superlattice-like MnBi2Te4/(Bi2Te3)n (n = 0, 1, 2, 3...) layered structure, present intri…
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…
