Heat and Current Annealing Effects on Magnetic Properties of Fe-rich Glass-Coated Amorphous Microwires with Different Radius

For Fe-rich glass-coated microwires to be a competitive option for magnetic technologies, the enhancing and tuning of their properties is necessary, and therefore, a better understanding of these processes is also needed. In this work, two Fe microwires with different geometries are subjected to both conventional and current annealings to study their effects. Results show a general enhancement of magnetic softness and domain wall dynamics after both treatments, also suggesting an earlier onset of crystallization in thin samples.
