μi-T curve of amorphous Fe74.5Cu1Nb2Si17.5B5 alloy.
μi-T curves of Fe74.5Cu1Nb2Si17.5B5 alloy annealed at 480 to 570 °C.
μi-T curves in successive heating-cooling cycles for as-quenched amorphous Fe74.5Cu1Nb2Si17.5B5 alloy. Numbers indicate the sequence of heating-cooling cycle. The heating steps ended at 480 °C, 510 °C, 540 °C, and 570 °C, respectively.
XRD patterns of as-quenched and annealed Fe74.5Cu1Nb2Si17.5B5 samples.
Hysteresis loops of Fe74.5Cu1Nb2Si17.5B5 samples annealed at 480 °C, 510 °C, 540 °C, and 570 °C with a field amplitude, Hm = 200 A/m.
