Abstract
An amorphous magnetic wire comprises a magnetically hard wire portion for propagating a magnetoelastic wave, and a magnetically soft wire portion for generating or detecting the magnetoelastic wave. This amorphous magnetic wire is obtained by producing a magnetic wire in an amorphous state, wire-drawing the amorphous magnetic wire so as to make the amorphous magnetic wire thinner, and annealing a portion of the magnetic wire to make the portion magnetically soft.
