Spin-momentum transfer between a spin-polarized current and a ferromagnetic layer can induce steady-state magnetization precession, and has recently been proposed as a …
We observe giant enhancement of microwave emission in MgO-based magnetic tunnel junction nano-oscillators through in-plane magnetic field orientation. At an optimal in-plane …

Low resistance-area product and high spin polarization lead to current-driven precession of the magnetization in Co Fe B∕ Mg O∕ Co Fe B magnetic tunnel junctions due to spin …
Spin-polarized current can excite the magnetization of a ferromagnet through the transfer of spin angular momentum to the local spin system. This pure spin-related transport …
We demonstrate the strong impact of the oscillator nonlinearity on the line broadening by studying spin-transfer-induced microwave emission in MgO-based tunnel junctions as a …

Heat-driven engines are hard to realize in nanoscale machines because of efficient heat dissipation. However, in the realm of spintronics, heat has been employed successfully—for …
The excitation of the steady-state precessions of magnetization opens a new way for nanoscale microwave oscillators by exploiting the transfer of spin angular momentum from a …
We have measured the bias voltage and field dependence of eigenmode frequencies in a magnetic tunnel junction with MgO barrier. We show that both free layer (FL) and reference …
