Abstract
Giant magnetoresistance of 7.7% at 5 K is observed in bulk mechanically alloyed Co30Ag70. Our recently defined δ(Δρ/ρ) technique used to determine the predominant interactions within the system indicated that negative interactions dominate between the particles. Exchange anisotropy and metastable magnetization processes characterized by large Barkhausen jumps are observed at low temperatures on a small volume of the sample.This publication has 12 references indexed in Scilit:
