Investigation of the local characteristics of amorphous electrical steel

Abstract

The local characteristics of amorphous electrical steel (foil) before and after exposure to weak (10–100 kA/m) low-frequency (10–20 Hz) magnetic-field pulses are studied by atomic force microscopy, scanning electron microscopy, and electron probe microanalysis. The research results show that, at certain magnetic-treatment parameters, the magnetic properties of the material change, while the concentrations of the phases present in it and the surface structure of the foil remain unchanged.
