Abstract
A magnetoresistive device has an alloy film, including a ferromagnetic substance and a non-magnetic substance which is not soluble in solid phase in the ferromagnetic substance or is in a eutectic relation with the ferromagentic substance. The ferromagnetic substance forms grains in the non-magnetic substance, and the grains preferably have anisotropic shapes. The non-magnetic substance is conducting. The alloy film is composed of a plurality of alloy film stripes. Alternatively the magneto-resistive device includes a non-magnetic layer arranged between first and second magnetic layers, wherein the non-magnetic layer has 10 to 50 weight percent of grains of a magnetic substance dispersed therein.
