The magnetization processes of the Fe80.5Cu1.5Si4B14 nanocrystalline alloy were observed by Kerr effect. In the specimen annealed with heating rate of 0.3°C/s (NA), the pinning of domain walls was observed. Owing to such pinning effect in the NA spe

Continuous stress-annealing process (CSA), in which a ribbon under tensile stress passes through a furnace, was carried out for obtaining long Fe–Cu–Nb–Si–B ribbons with creep-induced anisotropy. It was clarified that the creep-induced anisot
