Anomalous Spin-Orbit Torques in Magnetic Single-Layer Films
, 2019 Spin-orbit interaction (SOI) couples charge and spin transport, enabling electrical control of magnetization. A quintessential example of SOI-induced transport is the anomalous Hall effect (AHE), first observed in 1880, in which an electric current ...

Current-Controlled Electrical Point-Source Stimulation of Embryonic Stem Cells [PDF]
Cellular and Molecular Bioengineering, 2009 Stem cell therapy is emerging as a promising clinical approach for myocardial repair. However, the interactions between the graft and host, resulting in inconsistent levels of integration, remain largely unknown. In particular, the influence of electrical activity of the surrounding host tissue on graft differentiation and integration is poorly ...
