Magnetization of Ni-Fe-Mo Electrolytic films at low temperatures

, and Jrwere measured on Ni-Fe-Mo films at low temperatures. As the temperature dropped from 300 to 80°K, the Hccoercive field of Ni-Fe-Mo films with 0 percent content of Mo decreases from 1800 to 680 A/m. On the contrary, for the films with 5 and 10 percent Mo, the Hcincreases. The magnetization Jsvaries with temperature in the same sense as Hc. From the curves at K and K, it is found that the Ni-Fe-Mo electrolytic films with a concentration of over 10 percent Mo present properties characteristic of the superparamagnetic state.
