Popis: Granular alloys of Fe x Cu x Ag 100–2 x ( x =15, 35) have been produced by mechanical alloying. The x =15 alloy is composed of Fe(Cu) and Ag nanocrystals, whereas the Fe 35 Cu 35 Ag 30 is amorphous. DC magnetisation and AC susceptibility (5–300 K) show a maximum about 150 K for the x =15 alloy. The magnetisation has been fitted using log-normal distribution of grain sizes. The effect of interparticle interactions is discussed.
