Abstract :
The magnetocrystalline anisotropy, the magnetostriction, and the structure-sensitive properties in the magnetization process were studied in the ordered-disordered states of Ni3Fe alloy. The single crystals were cooled very slowly at the rate of 1°C/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 disk specimens. The magnetic domain was also observed. The experimental results obtained in the ordered state are considerably different from those obtained by previous investigators. The difference is attributed to the degree of order-the magnetic properties obtained by previous investigators are those of a partially ordered state
