A low-power spin-torque nano-oscillator (STNO)-based wireless communication is demonstrated with a 180 nm CMOS transmitter and receiver. The ON–OFF keying (OOK) modulation is employed to overcome the inherent drawbacks of the STNO, such as low outp

The inverse Faraday effect was initially discovered with dielectric paramagnets and recently extended to metallic ferromagnets, and it has been considered as one of the key mechanisms for the optical manipulation of the magnetization. Two different e

We study spin-orbit-torque-driven ferromagnetic resonance (FMR) in ferromagnetic (FM) bilayers, consisting of Co and permalloy (Py), sandwiched between Pt and MgO layers. We find that the FM layer in contact with the Pt layers dominantly determines t

We examined electrical spin transport in cylindrical silicon nanowires (Si NWs) using the lateral nonlocal spin-valve (NLSV) geometry with CoFeB/MgO contacts. The use of a thin MgO layer as the tunnel barrier in the NLSV devices provided an optimum r
