We present a numerical macrospin model for harmonic voltage detection in multilayer spintronic devices. The core of the computational backend is based on the Landau-Lifshitz-Gilbert-Slonczewski equation, which combines high performance with satisfactory, for large-scale applications, agreement with the experimental results. We compare the simulations with the experimental findings in Ta/CoFeB bilayer system for angularand magnetic field-dependent resistance measurements, electrically detected…

Spin-torque diode effect in magnetic tunnel junctions

TLDR
It is shown that the application of a small radio-frequency alternating current to a nanometre-scale magnetic tunnel junction can generate a measurable direct-current voltage across the device when the frequency is resonant with the spin oscillations that arise from the spin-torque effect.
