文摘

Resistivity minimum in as-prepared and annealed Cu-Co microwires associated to the Kondo-like behavior. Enhancement of the influence of magnetic field on Resistivity after annealing. Remarkable improvement of magnetoresistance after annealing. Considerable effect of annealing on temperature dependence of the resistivity. Remarkable effect of annealing on magnetization curves and structure.
