The temperature dependence of angular correlation annihilation radiation (ACAR) in Invar Fe–Ni alloys is investigated. It is found that the ACAR distribution in the Curie temperature region TC depends on temperature. This effect is created only by

It is shown that the model of two magnetic states of Fe atoms in Invar Fe–Ni alloys allows a comprehensive interpretation of effect of deviation of average magnetic moment per atom 〈 m ( c Fe )〉 from the Slater–Pauling curve. In the model und

2014 The saturation magnetization and electrical resistance of binary Fe-Ni alloys, with 38 and 45 % Ni, were studied as a function of pressure. The pressure was created by freezing water in a beryllium bronze bomb. Measurements were made from 1,7 to
