High power and low critical current density spin transfer torque nano-oscillators using MgO barriers with intermediate thickness
Reported steady-state microwave emission in magnetic tunnel junction (MTJ)-based spin transfer torque nano-oscillators (STNOs) relies mostly on very thin insulating barriers [resulting in a resistance × area product (R × A) of ~1 Ωμm(2)] that can sustain large current densities and thus trigger larg...
