✦ Synopsis

Resistive transitions of single crystal Ba~YCus_=Ni=Or were studied in magnetic fields up to 20 tesla. For dopant concentrations of z = 0.01 and z --0.03, the transition temperature in zero field decreased from the undoped value of 88 K to 82 K and 76 K respectively, while the transition width AT (10%-90%) is still less than 1 K. Moreover, Ni-doping has a dramatic effect on the resistive transition, tending to suppress the field dependent broadening.
