Xiao Wang,Jian Tang,Xiuxin Xia,Xiuxin Xia,Congli He,Junwei Zhang,Junwei Zhang,Yizhou Liu,Caihua Wan,Chi Fang,Chenyang Guo,Wenlong Yang,Yao Guang,Xiaomin Zhang,Hongjun Xu,Jinwu Wei,Mengzhou Liao,Xiaobo Lu,Jiafeng Feng,Xiaoxi Li,Xiaoxi Li,Yong Peng,Hongxiang Wei,Rong Yang,Dongxia Shi,Xixiang Zhang,Zheng Han,Zheng Han,Zhidong Zhang,Zhidong Zhang,Guangyu Zhang,Guoqiang Yu,Xiufeng Han +32 more
TL;DR: A bilayer structure of Fe3GeTe2/Pt is devised, in which the magnetization of few-layered Fe3 GeTe2 can be effectively switched by the spin-orbit torques (SOTs) originated from the current flowing in the Pt layer.

High Spin Hall Conductivity in Large-Area Type-II Dirac Semimetal PtTe2
Hongjun Xu,Jinwu Wei,Hengan Zhou,Jiafeng Feng,Teng Xu,Haifeng Du,Congli He,Yuan Huang,Junwei Zhang,Yizhou Liu,Han-Chun Wu,Chenyang Guo,Xiao Wang,Yao Guang,Hongxiang Wei,Yong Peng,Wanjun Jiang,Guoqiang Yu,Xiufeng Han +18 more
TL;DR: A manufacturable recipe is developed to fabricate large-area thin films of PtTe2 , a type-II Dirac semimetal, to study their capability of generating SOT and it is demonstrated that the SOT from PtTe1 layer can switch a perpendicularly magnetized CoTb layer efficiently.

Yan,Jiafeng Feng,Caihua Wan,Jinwu Wei,Xiao Wang,Xiaomin Zhang,Hongjun Xu,Chenyang Guo,Hongxiang Wei,Giovanni Finocchio,Xiufeng Han,Gisela Schütz +24 more
TL;DR: Two advanced X-ray techniques are applied, based on magnetic circular dichroism, to investigate the spin textures of skyrmions in [Ta/CoFeB/MgO]n multilayers, and it is demonstrated that the chirality of the magnetic structure undergoes a depth-dependent evolution.
Journal ArticleDOI
An induction method to calculate the complex permeability of soft magnetic films without a reference sample.
TL;DR: A new analytical method using the short-circuited microstrip line can exhibit higher sensitivity and a wider frequency band than coplanar waveguide and pick-up coil and the complex permeability spectra can be calculated without a known reference sample.
