Abstract
In order to increase the power which can be passed to a spin valve element, an insulating layer 24 or a nonmagnetic layer 51 is sandwiched by ferromagnetic layers 23, 25, and a porous layer 10(10′) having a plurality of minute holes is placed so as to be in contact with one of the ferromagnetic layers, or near the ferromagnetic layer with another layer intervening. By this means, even when a single-domain magnetic multilayer film extending over a broad region is not used, when, for example, microwave oscillation is induced by means of the spin valve element, the microwave power can be increased.
