چکیده انگلیسی
Composition, structure and giant magnetoresistance in FexCuyNiz films prepared at different sputtering pressures were investigated. X-ray diffraction studies showed only Cu (1Â 1Â 1) peak from the Cu grain. The shifts in the d-spacing d111 of Cu indicates a progressive substitution of Ni in the Cu lattice. Similar trends in d111 of Cu observed for the samples prepared at different sputtering pressures indicate that the structural behaviour of the samples is nearly independent of the sputtering pressure. A significant enhancement of magnetoresistance (MR) for the samples sputtered at 0.001Â mbar as compared to that sputtered at 0.02 mbar is attributed to the reduced role of residual gas impurities in the films upon lowering the sputtering pressure. An interesting observation is that the MR did not significantly decrease even with a large substitution of Ni in the Cu grains.
