Magnetic properties of multilayer films composed of FeRhIr (or FeRh), Ag and Fe layers were investigated in detail. The results showed that the multilayer film with structure exhibits a very unique magnetic phase transition, where the transition temperature was subject to change from 40 to 170 °C by the application of a magnetic field ranging from 250 to 150 Oe. The change in pinning strength of magnetization in antiferromagnetic and ferromagnetic phases of FeRhIr layers with a magnetic field is considered to be responsible for the unique properties. Associated with the magnetic phase transition of FeRhIr layers, magnetostrictive response of the film was actually obtained by applying a magnetic field up to 100 Oe.
