摘要：
A spin torque oscillator is described in which the conventional Field Generation Layer (FGL) is replaced by a bilayer, one of whose members exhibits perpendicular magnetic anisotropy while the other exhibits conventional in-plane anisotropy. Provided the layer with the perpendicular anisotropy is the one that is closest to the spacer layer, the device is able to generate microwaves at current densities as low as 1×108 A/cm2.
