Определение знака магнитострикции насыщения аморфных сплавов на основе взаимодействия поверхности ленты с водой

Abstract

The influence of ribbon surface interactions of amorphous soft magnetic Co-Fe-Ni-Cr-Si-B (АМАГ-172) alloy with water on the magnetization distribution in the ribbon was studied. The possibility of ribbon surface treatment with water to determine the sign of the saturation magnetostriction is shown. It is established that heat treatment in air at 380 оC, with the isothermal holding 40 and 10 minutes forms the ribbon state with s>0 in the first case and with s<0 in the second case.
