abstract={Nano crystallization of Ni<SUB>0.5</SUB>Fe<SUB>0.5</SUB>Zr<SUB>3</SUB> metallic glasses was achieved by isothermal annealing over the temperature range 673-1173K. The crystallization precedes with the formation of metastable fcc (FeZr<SUB>2</SUB>+NiZr<SUB>2</SUB>) + stable bct (FeZr<SUB>2</SUB>+NiZr<SUB>2</SUB>) to stable bct (FeZr<SUB>2</SUB>+NiZr<SUB>2</SUB>). The resistivity (<i>¦Ñ</i>) of the amorphous and fully crystallized states of Ni<SUB>0.5</SUB>Fe<SUB>0.5</SUB>Zr<SUB>3</SUB> metallic glasses was investigated over the temperature range 2-300k. The temperature dependence of the resistivity (<i>¦Ñ</i>(T)) for the amorphous state is well described by the Mizutani's equation as group 4 metallic glasses with the Fermi level in the d band; while <i>¦Ñ</i>(T) for the fully crystallized states show a negative deviation from linearity. The amorphous and crystalline states have displayed superconductive transitions at low temperatures. Enhancement in the superconducting transition temperature (<i>T</i><SUB><i>c</i></SUB>) in comparison to the amorphous state was observed in the fully crystallized states.},
