Abstract: The magnetic aftereffect (MAE) and the positron lifetime were measured at room temperature on the Fe73.5Cu1Nb3Si13.5B9 alloy in as-cast and after annealing at temperature T-a in the range from 450 to 750℃. It was found that both the MAE and the positron lifetime decrease with increasing T-a when T-a less than or equal to 600 degrees C. While T-a greater than or equal to 650℃, MAE is essentially suppressed, and two positron lifetimes appear.
