FIG. 1.

A TEM bright-field plan-view image of an ex situ annealed ribbon. The inset is an image at a low magnification of the same sample.

FIG. 2.

(a) curve of field-annealed ribbons measured in upon heating up to . The inset is an enlarged curve (in the range ) for upon heating and cooling up to and down from ; (b) Coercivity dependence on the temperature of the field-annealed ribbon; (c) demagnetization curves for as-spun and field-annealed samples.

Image of FIG. 3.
FIG. 3.
