Abstract

Magnetic measurements in Ni50Mn50-xInx alloys were performed in order to investigate the effect of the degree of order on the magnetic properties for specimens annealed at different temperatures. It was confirmed that Curie temperature, TC, and spontaneous magnetization, μm, in as-quenched specimens with a low degree of order exhibited composition dependence of indium basically similar to those in as-annealed ones with a high degree of order reported in a previous paper. However, especially in the In-rich region of x > 25, both the TC and the μm obtained from the as-quenched specimens were lower than those from the as-annealed specimens.
