Abstract
The nano Ni-Cr thin-film samples with different composition have been fabricated by a double-target magnetron co-sputtering equipment, through controlling the sputtering power, the substrate rotate speed, and the substrate temperature, The results showed that the grains sizes with polycrystalline microstructure were not greater than 10 nm. The crystal microstructure of Ni-Cr thin-films is Face Centered Cubic (FCC). The dominant texture in the Ni-Cr film was Ni (111) under this sputtering condition. The lattice parameters of Ni crystal and the inter-planar distances of Ni (111) increased by Cr solid-soluble in Ni crystal. The surface morphology of the thin-film samples is smooth and compact. The TCR (temperature coefficient of resistance) value of specimen 3 was 84~130 ppm/k, which show the specimen 3 was the most stable.
