摘要: A spin-torque oscillator (STO) has increased magnetic damping of the oscillating free ferromagnetic layer. The Gilbert parameter (a) is at least 0.05, and preferably greater than 0.05. layer may be a any type conventional material, but contains one or more elements as dopant. element selected from group consisting Pt, Pd 15 lanthanide elements. also by adjacent One an antiferromagnetic like Mn alloy. As modification to layer, bilayer formed nonmagnetic metal electrically conductive separation between Another lanthanides.
