ABSTRACT:
A magneto-resistive element includes a lower magnetic shield film and a magneto-resistive film disposed above the lower magnetic shield film. The lower magnetic shield film includes a lower shield layer and an upper shield layer. The upper shield layer is amorphous or microcrystalline, made of a NiFe or CoFe composition containing B or P, and deposited on the lower shield layer. The lower shield layer is a magnetic conductive layer which is amorphous or microcrystalline with a crystal grain size equal to or less than 20 nm.
