The nanocrystalline state of Fe86Zr7Cu1B6 has been achieved using conv
entional heat treatment as well as Joule heating. Hysteresis loop meas
urements were performed on-both types of sample, Additionally, the tem
perature dependence of the coercivity of Fe86Zr7Cu1B6 annealed at diff
erent temperatures was measured and compared with that of a Joule-heat
ed sample.
