Mössbauer spectra were taken at room temperature on rolled Vicalloy samples in (i) a state obtained by quenching the sample from 950°C; (ii) a state obtained by annealing for optimum permanent magnet properties. Annealing results in a narrowing of the absorption peaks, an increase in hyperfine field, and the appearance of an additional absorption peak indicative of a paramagnetic phase. These results are interpreted in terms of the known phase diagram of FeSingle Bond signCoSingle Bond signV, and lend support to the description of Vicalloy magnets as fine-particle magnets.
