Figure 1: Cross-sectional view of a nanopillar spin-valve device. For an idealized model in which the free-layer magnetization behaves as a single domain, the Néel–Brown prediction for the activation ...

Approaching the timescales of the underlying elementary processes 1,2, spin currents (SCs) with femtosecond pulse duration 3,4,5 can provide valuable fundamental insights into the ultrafast spin ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field ...
