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.
(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.
(a) Room-temperature perpendicular resistivity data for an as-spun Mn-Bi ribbon and an ex situ annealed ribbon. (b) Room-temperature perpendicular magnetoresistance data and fits to these MR data using the Pippard-Fawcett two-carrier expression for the ribbons shown in (a).
