Journal ArticleDOI
Layer-dependent ferromagnetism in a van der Waals crystal down to the monolayer limit
Bevin Huang,Genevieve Clark,Efrén Navarro-Moratalla,Dahlia R. Klein,Ran Cheng,Kyle L. Seyler,Ding Zhong,E. R. Schmidgall,Michael A. McGuire,David Cobden,Wang Yao,Di Xiao,Pablo Jarillo-Herrero,Xiaodong Xu +13 more
TL;DR: Xu et al. as mentioned in this paper used magneto-optical Kerr effect microscopy to show that monolayer chromium triiodide (CrI3) is an Ising ferromagnet with out-of-plane spin orientation.
Journal ArticleDOI
Van der Waals engineering of ferromagnetic semiconductor heterostructures for spin and valleytronics
Ding Zhong,Kyle L. Seyler,Xiayu Linpeng,Ran Cheng,Nikhil Sivadas,Bevin Huang,E. R. Schmidgall,Takashi Taniguchi,Kenji Watanabe,Michael A. McGuire,Wang Yao,Di Xiao,Kai-Mei C. Fu,Xiaodong Xu +13 more
TL;DR: The photoluminescence detection of valley pseudospin provides a simple and sensitive method to probe the intriguing domain dynamics in the ultrathin magnet, as well as the rich spin interactions within the heterostructure.
Journal ArticleDOI
Spin pumping and spin-transfer torques in antiferromagnets.
TL;DR: In this paper, the authors derived pumped spin and staggered spin currents in terms of the staggered field, the magnetization, and their rates of change, and connected the pumped currents to current-induced torques via Onsager reciprocity relations.
Journal ArticleDOI
Terahertz Antiferromagnetic Spin Hall Nano-Oscillator
Ran Cheng,Di Xiao,Arne Brataas +2 more
TL;DR: The combined effect of spin pumping and current-induced torques introduces a dynamic feedback that sustains steady-state oscillations with amplitudes controllable via the applied current in insulating antiferromagnets.
Journal ArticleDOI
Spin Nernst effect of magnons in collinear antiferromagnets
TL;DR: It is found that magnons around the Γ point and the K point contribute oppositely to the transverse spin transport, and their competition leads to a sign change of the spin Nernst coefficient at finite temperature.
