<p>In order to increase the power which can flow into a spin-valve element, an insulating layer (24) or a non-magnetic layer is sandwiched by ferromagnetic layers (23, 25) and a porous layer (10(10')) having a plenty of micro pores is arranged in contact with one of the ferromagnetic layer or between the ferromagnetic layers via other layer. Thus, it is possible to increase the power of the microwave when oscillating a microwave by a spin-valve element, for example, without using a magnetic multi-layered film of a wide-region single magnetic domain.</p> |
