Magnetic Properties and Temperature Stability of Nanocrystalline Fe-Based Soft Magnetic Alloys
The effect of the nanocrystallization conditions on the structure, magnetic characteristics and temperature stability of the Fe73.5Cu1Nb3Si13.5B9, Fe73.5Cu1Nb1.5Мo1.5Si13.5B9, Fe69Cu1Nb1.5Мo1.5Si13.5B9Co4.5, and (Fe0.6Co0.4)86Hf7B6Cu1 nanocrystalline soft magnetic alloys has been analyzed. The samples were nanocrystallized in the absence of a field, in a dc or ac magnetic field. It has been shown that the Fe73.5Cu1Nb1.5Мo1.5Si13.5B9 alloy has unique magnetic properties and a high temperature-time stability. It has been found that nanocrystallization of the (Fe0.6Co0.4)86Hf7B6Cu1 amorphous alloy in an ac magnetic field considerably improves its static and dynamic magnetic properties.
