Abstract
Magnetic aftereffect measurements were performed on Nd-Fe-B magnets at short times. The variation of magnetization is found to be linear with ln t as predicted by the theory. χirr (H) was also measured for different rates of variation of the applied field and the difference in the position of the maximum is discussed.
