The composition, phase structure, and microstructure of the discontinuous multilayer films [NiFeCo(10 nm)/ Ag(10 nm)]×20 annealed at temperature 280, 320, 360 and 400℃, respectively were investigated. GMR (giant magnetore-sistance) ratios of the multilayer films were measured at different temperatures. The results showed that FeNi3 precipitated at 360℃ and dissolved at 400℃. The films annealed at 360℃ for 1 h exhibited the highest GMR ratio 11% when saturation field was equal to 79.6 kA/m.
