Abstract
We compare the magnetic anisotropy induced by thermomagnetic treatments in some amorphous metallic alloys, considered in three different states : as-received, annealed, annealed and subsequently quenched. The atomic mobility is shown to decrease during an anneal, and to be partially restored by a quench. It is concluded that some processes involved in what is called "structural relaxation" are reversible, at least in part.
