Spin-orbit torque (SOT) magnetization switching is a phenomenon induced by a spin current, which is in turn generated by a charge current. Eliciting this phenomenon could help to manipulate the magnetization in spintronic ...
A team of physicists has discovered an electrical detection method for terahertz electromagnetic waves, which are extremely difficult to detect. The discovery could help miniaturize the detection equipment on microchips and ...
