The effects of short range order on the structural and transport properties of the $ rm Cu sb{1-x}Ni sb{x}Zr sb2$ amorphous metallic alloy system are studied. Depending on composition, these amorphous alloys crystallize into different structures. CuZr$ sb2$ has the I4/mmm (C11) structure and NiZr$ sb2$ has the I4/mcm (C16) structure. It is believed that the short range order in the amorphous phase is related to the final crystalline phase. A careful study (using differential scanning calorimetry, X-ray diffraction on as made and crystallized states, room temperature magnetic susceptibility and resistivity, and a determination of the superconducting transition temperature of as-made and annealed states) has been done to see what transport properties are affected. / It is observed that there is a linear increase in the values of the susceptibility, resistivity, and superconducting transition temperature of the system from CuZr$ sb2$ to NiZr$ sb2.$ This is attributed to an increase of the electronic density of states as the concentration of Ni increases. There is little or no influence on transport properties due to topological short range order.
