The phase state, electrical conductivity and magnetoresistive properties of binary film alloys based on Fe, Co and Ni prepared by the method evaporation in high vacuum in the temperature range 100700 K have been studied. It has been shown that the fcc-phase is observed for as-deposited and annealed up to 700 K Fe0,50Ni0,50 thin films with a thickness d 10100 nm, the fcc-phase is observed. For Fe0,67Ni0,33 Fe0,50Co0,50 and Fe0,67Co0,33 thin films, the bcc-phase is fixed. It was found that the size dependences of the resistivity, temperature coefficient of resistance and magnetoresistance are realized for all structurally continuous film alloys. The character of size dependences is а like the corresponding dependences for the pure metal films. It has been shown that for Fe0,67Ni0,33, Fe0,50Co0,50 and Fe0,67Co0,33 the size dependences of both longitudinal and transverse magnetoresistance appear much weaker than for Fe0,50Ni0,50 thin alloy. For Fe0,67Ni0,33, Fe0,50Co0,50 and Fe0,67Co0,33 thin alloys, the value of both longitudinal and transverse magnetoresistance is weakly depending on the temperature. |
