Abstract
Measurements have been made of the magnetization, electrical resistance and specific heat of the alloy Ni3Mn during the progress and after the completion of a variety of heat treatments. The evidence indicates that at 510° c. an order-disorder transformation occurs, and that the ordered structure is ferromagnetic with a Curie point at 460° c. The sharp decrease of resistance on slow cooling takes place at the Curie point. The effect of the degree of order and of the size of the ordered regions on the resistance and the magnetization is discussed in the light of the experimental results.Keywords
