Abstract The D. C. and A. C. methods are used for the measurement of the magnetic properties of 50pct. nickel and 50 pct. iron Ni-Fe alloy. The ratio between the remanence and the magneticsaturation induction, B_r/B_s, and the coercive force, H_c, are taken as a criterion for assessing themagnetic characteristics of the alloy. The samples used in the experiments are cold-rolled with (Ⅰ) 94 per cent, (Ⅱ) 98 per cent and(Ⅲ) 99 per cent reductions. The class Ⅰ and class Ⅱ samples are annealed at (1) 900°, (2) 1000°, (3)1100°, (4) 1200° and (5) 1300℃ for one hour. The class Ⅲ samples are annealed at 1100℃ for(1) 30 minutes, (2) one hour, and (3) one and half an hour respectively. The formation of the cubic texture of the alloy has been studied by the X-ray pole figuremethod and the results Will be presented in another paper. The development of the material used for the magnetic amplifiers is finally discussed.
