Effect of annealing on magnetization process of Ni/sub 3-x/Fe/sub 1+x/ (-0.2

The magnetocrystalline anisotropy, the magnetostriction and the structure-sensitive properties in the magnetization process were studied in the ordered and disordered states of specimens between 70.1 wt% Ni and 79.7 wt% Ni. The single crystals were cooled at the rate of 1 K/day to obtain the fully ordered state. Magnetization curves and hysteresis loops were measured using picture frame specimens. The magnetocrystalline anisotropy and the magnetostriction were also measured in disc specimens. New experimental results obtained in the order state are considerably different from those obtained by previous investigators. The difference is attributed to the degree of order and the magnetic properties of the previous investigators are those of a partially ordered state.<>
