Gamma-irradiation influence on the initial magnetic conductivity of   based on the system Fe-Si-B amorphous and nanocrystalline alloys
  The dependence of initial magnetic permeability {\mu}i of based on the Fe-Si-B amorphous and nanocrystalline alloys on the {\gamma}-irradiation dose was investigated by the method of inductance factor determination. It was determined that the alloying of amorphous Fe-Si-B alloys by nickel and molybdenum increases the radiation sensitivity of the {\mu}i. Initial magnetic permeability of nanocrystalline magnetic alloys is less sensitive to the action of {\gamma}-irradiation as compared with the alloyed amorphous alloys. Has been suggested that radiation influence on the initial magnetic permeability are caused by creation of non-magnetic incorporation in structure of amorphous alloys as well as amorphous matrix of nanocrystalline alloys.
