摘要
Results of chi(ac)(T) in powder oriented samples of R2Fe14BHx, (R = rare earth) very often show peaks, approximately between 100 and 300 K, when the exciting ac field is parallel to the easy axis. This work presents the existence of time effects as well as thermal hysteresis on these anomalies. An explanation of this phenomenon is given in terms of the extrinsic contributions to chi(ac)(T).
