- 論文の詳細を見る
M6ssbauer and magnetic measurements were made on Fe~;o particles pre-cipitated in a Cu matrix in order to investigate magnetic properties of fcc Fe~:o alloys around the concentration for the ferromagnetic to antiferromagnetic transition, using the samples Cugs(Fel-*Co*)2 with x=0.3-0.45. The anti-ferromagnetic fcc F~Co with a small moment was observed at x =0.3, whereas the ferromagnetic fcc Fe-Co with nearly the full moment appears and cocxists with the antiferromagnetic fcc Fe-Co for x =0. 35-0.4. The antiferromagnetic F~Co disappears around x =0.45. This sharp magnetic transition associated with a small change in the composition is quite similar to the case of Fe-Ni Invar alloys.
