Embodiment Construction
[0038] The present invention will now be described with reference to the accompanying drawings.
[0039] Before describing the embodiment of the present invention, lets us summarize the present invention as follows.
[0040] According to the present invention, there is provided a magnetoresistive effect element having an arrangement in which a pair of ferromagnetic material layers is opposed to each other through an intermediate layer so that a magnetoresistive change is obtained by causing a current to flow in the direction perpendicular to the layer surface. In this magnetoresistive effect element, the ferromagnetic material layers are annealed by anneal including rotating field anneal and the following static field anneal.
[0041] According to the present invention, in the magnetoresistive effect element, at least one of the ferromagnetic material layers is made of an amorphous or microcrystal material.
[0042] According to the present invention, the magnetoresistive effect element is ...
