Abstract
The magnetic properties of Fe77R15B8 powders have been measured as a function of particle size in the temperature range 77–300 K. The coercivity is found to increase first with particle size to a maximum value and then to decrease again. This behavior is explained with the single domain particle theory. The peak values of coercivity obtained in the various alloys are found to scale with the anisotropy field. The temperature coefficients of coercivity are smaller than those observed in sintered magnets.Keywords
