비정질 Fe-Co-Re-B(RE=Nd, Sm, Gd, Tb) 합금의 자기적 성질
A Study on the Magnetic Properties of Amorphous Fe-Co-RE-B (RE=Nd, Sm, Gd, Tb) Alloys

희토류-3d 천이원소인 비정질
The temperature-dependent magnetization curves of amorphous Fe-Co-(Nd, Sm, Gd, Tb)-B alloys were measured using a vibrating sample magnetometer from 77 K up to 900 K. The spin wave stiffness constants and the range of the exchange interaction were calculated from the saturation magnetization values at 0 K. Curie temperatures and the Bloch coefficients estimated from the saturation magnetization curves. The low temperature dependence of magnetization is in good agreement with Bloch relation,
