Coercivity analysis of melt-spun Sm2(Co,Fe,Cu,Zr)17
Source abstract
Abstract
Abstract The temperature dependence of magnetic properties of two types of melt-spun Sm 2 (Co,Fe,Cu,Zr) 17 ribbon, initially subjected to different magnetic hardening regimes, has been investigated for temperatures from 4 to 300 K. An analysis of magnetic viscosity showed significant differences in the activation volumes v a and magnetic viscosity coefficients S v which could be related to the anomalous temperature coefficient of coercivity observed for one type of the magnets and the conventional behaviour observed in the second type.
