Electric-field Control of Magnetism with Emergent Topological Hall Effect in SrRuO3 through Proton Evolution
Zhuolu Li, Shengchun Shen, Zijun Tian +16
Ionic substitution forms an essential pathway to manipulate the carrier density and crystalline symmetry of materials via ion-lattice-electron coupling, leading to a rich spectrum…
Thermally Driven Topology in Frustrated Systems
Jie-Xiang Yu, Morgan Daly, Jiadong Zang
Non-trivial topology in a two-dimensional frustrated spin system with the Dzyaloshinskii-Moriya (DM) interaction was investigated by Monto Carlo simulations. At finite temperatures…
Topological Hall Effect in Magnetic Topological Insulator Films
Jian-Xiao Zhang, Domenico Andreoli, Jiadong Zang +1
Geometric Berry phase can be induced either by spin-orbit coupling, giving rise to the anomalous Hall effect in ferromagnetic materials, or by chiral spin texture, such as skyrmion…
Binding a Hopfion in Chiral Magnet Nanodisk
Yizhou Liu, Roger Lake, Jiadong Zang
Hopfions are three-dimensional (3D) topological textures characterized by the integer Hopf invariant . Here, we present the realization of a zero--field, stable hopfion spin t…
Giant perpendicular magnetic anisotropy in Fe/III-V nitride thin films
Jie-Xiang Yu, Jiadong Zang
Large perpendicular magnetic anisotropy (PMA) in transition metal thin films provides a pathway for enabling the intriguing physics of nanomagnetism and developing broad spintronic…
Planar Hall effect in antiferromagnetic MnTe thin films
Gen Yin, Jie-Xiang Yu, Yizhou Liu +3
We show that the spin-orbit coupling (SOC) in alpha-MnTe impacts the transport behavior by generating an anisotropic valence-band splitting, resulting in four spin-polarized pocket…
