Chiral Spin-Wave Velocities Induced by All-Garnet Interfacial Dzyaloshinskii-Moriya Interaction in Ultrathin Yttrium Iron Garnet Films

Haiming Yu, Song Liu, Peng Gao, Dirk Grundler, Ping Che, Yuehui Li, Sa Tu, Jilei Chen, Jianyu Zhang, Tao Liu

Spin waves can probe the Dzyaloshinskii-Moriya interaction (DMI), which gives rise to topological spin textures, such as skyrmions. However, the DMI has not yet been reported in yttrium iron garnet (YIG) with arguably the lowest damping for spin waves. In ...

Regulating the anomalous Hall and Nernst effects in Heusler-based trilayers

Jean-Philippe Ansermet, Simon Granville, Haiming Yu, Song Liu, Sa Tu, Junfeng Hu

Anomalous Hall and anomalous Nernst properties of thin MgO/Co-2Fe0.4Mn0.6Si/Pd stacks with perpendicular magnetic anisotropy (PMA) revealed the presence of the magnetic proximity effect (MPE) in the Pd layer. The MPE is evidenced by nanometer range thickne ...

Record thermopower found in an IrMn-based spintronic stack

Jean-Philippe Ansermet, Haiming Yu, Song Liu, Peng Gao, Sa Tu, Junfeng Hu, Jianyu Zhang, Yao Zhang

The Seebeck effect converts thermal gradients into electricity. As an approach to power technologies in the current Internet-of-Things era, on-chip energy harvesting is highly attractive, and to be effective, demands thin film materials with large Seebeck ...
