Abstract
The anomaly detected in the magnetic a.c. susceptibility of many inter metallic compounds between 100 and 300 K, and in particular in Nd2Fe14 B at 220 K, has been induced in a controlled manner by thermal anneali ng. The anomaly has been interpreted in terms or thermal activated pro cesses of defects imposing their dynamical behavior on the domain wall s coupled to them, thus solving the controversy on its origin.
