A CPP giant magnetoresistive element includes a multilayer film including
a lower pinned magnetic layer having a laminated ferrimagnetic structure
including a lower first pinned magnetic sublayer, a lower nonmagnetic
intermediate sublayer, and a lower second pinned magnetic sublayer; a
lower nonmagnetic layer; a free magnetic layer; an upper nonmagnetic
layer; and an upper pinned magnetic layer having a laminated
ferrimagnetic structure including an upper second pinned magnetic
sublayer, an upper nonmagnetic intermediate sublayer, and an upper first
pinned magnetic sublayer disposed in that order. Each of the free
magnetic layer and the lower and upper second pinned magnetic sublayers
is composed of a NiFeX alloy or NiFeCoX alloy, X being an element which
decreases the saturation magnetization of a NiFe or NiFeCo base.
