A comparative study on as cast and annealed rare earth bulk metallic glass
(BMG) with composition Tb36Sm20Al24Co20 has been carried out by magnetization
measurements. The as cast amorphous sample shows non-ergodic magnetization but
does not show the behavior expected from magnetic glass. After annealing, the
partially crystallized BMG shows this magnetic glass behavior. This is
confirmed by the established measurement protocol of cooling and heating in
unequal fields (CHUF).
