Magnetic properties of amorphous Fe-Er-B-Si ribbons

Abstract
We report on our magnetic studies of amorphous (Fe1−x Erx)80B12Si8 ribbons with 0<xTC decrease. For instance, for x=0.125, the magnetization has fallen from the initial value of 175 to 108 emu g1 and TC from 660 to 500 K. In‐plane hysteresis loops show practically zero remanence and low coercivity of 1.0 Oe.
