Hysteresis loops of strain annealed at a frequency of 1 kHz. Shaded regions represent energy stored at the same magnetizations.
Hysteresis loops measured at 1 kHz, (a) , (b) , and (c) .
(a) of Fe-based and Co-based alloys, (b) of Co-based alloys with inset showing comparison of 300 MPa ribbons, (c) , and (d) the anisotropy per unit stress () and calculated assuming using Eq. (1). Data on FINEMET included for comparison (from Ref. 23).
XRD patterns of strain annealed (a) , (b) , and (c) . Unless otherwise noted, the ribbons were annealed at . Insets show subtracted patterns.
