ABSTRACT:
A magnetoresistive element includes a substrate, and a plurality of fine line structures, which are provided on the substrate to be substantially parallel to each other, and which each have an aspect ratio greater than 1. Each fine line structure has a multilayer structure of a first ferromagnetic layer, a non-magnetic conductive layer and a second ferromagnetic layer. Magnetic moments of the first and second ferromagnetic layers orient antiparallel to each other in a state with no external magnetic field being applied.
