Superconductivity, Antiferromagnetism, and Kinetic Correlation in Strongly Correlated Electron Systems by Takashi Yanagisawa

Topological orbital Hall effect caused by skyrmions and antiferromagnetic skyrmions by Börge Göbel, Lennart Schimpf, Ingrid Mertig

“…The topological Hall effect is accompanied by a topological orbital Hall effect even for s electrons without spin-orbit coupling. As we show, antiferromagnetic skyrmions and antiferromagnetic bimerons that have a compensated emergent field, exhibit a topological orbital Hall conductivity that is not accompanied by charge transport and can be orders of magnitude larger than the topological spin Hall conductivity. …”

Electrical mutual switching in a noncollinear-antiferromagnetic–ferromagnetic heterostructure by Ju-Young Yoon, Yutaro Takeuchi, Ryota Takechi, Jiahao Han, Tomohiro Uchimura, Yuta Yamane, Shun Kanai, Jun’ichi Ieda, Hideo Ohno, Shunsuke Fukami

“…Using a noncollinear-antiferromagnetic/nonmagnetic/ferromagnetic Mn3Sn/Mo/CoFeB heterostructure at zero magnetic field, we show current-induced switching in the CoFeB layer due to the spin current polarized by the magnetic structure of the Mn3Sn; by properly tuning the driving current, the spin current from the CoFeB further reverses the magnetic orientation of the Mn3Sn, which determines the polarity of the subsequent switching of the CoFeB. …”

Antiferromagnetic semimetal terahertz photodetectors enhanced through weak localization by Dong Wang, Liu Yang, Zhen Hu, Fang Wang, Yage Yang, Xiaokai Pan, Zhuo Dong, Shijian Tian, Libo Zhang, Li Han, Mengjie Jiang, Keqin Tang, Fuxing Dai, Kai Zhang, Wei Lu, Xiaoshuang Chen, Lin Wang, Weida Hu

“…Here, we investigate the terahertz detection capabilities of the two-dimensional antiferromagnetic semimetal NbFeTe2. Our study reveals that the interaction between antiferromagnetic magnetic moments and electron spin induces disordered carriers to hop between localized states, resulting in a nonlinear increase in responsivity as temperature decreases. …”
