Abstract

The superparamagnetic relaxation of a FINEMET-type alloy has been studied. It is demonstrated that this behaviour is a general feature of these nanocrystalline alloys. Since the practical requisite for observing superparamagnetic relaxation in these nanocrystalline alloys is the absence of interactions between the grains, the crystalline volume fractions approaching this optimal condition are those that produce a slight increase in coercivity measured at room temperature.
