Query: Dependence of spin torque diode voltage on applied field direction   The optimum condition of an applied field direction to maximize spin torque
diode voltage was theoretically derived for a magnetic tunnel junction with a
perpendicularly magnetized free layer and an in-plane magnetized pinned layer.
We found that the diode voltage for a relatively small applied field is
maximized when the projection of the applied field to the film-plane is
parallel or anti-parallel to the magnetization of the pinned layer. However, by
increasing the applied field magnitude, the optimum applied field direction
shifts from the parallel or anti-parallel direction. These analytical
predictions were confirmed by numerical simulations.
