| Description/Abstract | Single crystal samples of Lu(Ni{sub 1{minus}x}Co{sub x}){sub 2}B{sub 2}C have been prepared for x=0{endash}0.09. In-plane electrical resistivity measurements show that the residual resistivity of these samples increases linearly with {ital x}, though by less than is observed for polycrystalline samples. T{sub c} is suppressed by the cobalt substitution (from 16.0 K for x=0 to 9.5 K for x=0.09), though magnetization measurements indicate that this is not due to pair breaking by magnetic impurities. The critical field H{sub C2}(T) decreases with increasing Co concentration, and has some anisotropy between H{parallel}c and H{perpendicular}c. The ratio of the coherence length to the mean-free path ({xi}{sub 0}/l) is estimated, and found to be approaching the dirty limit ({xi}{sub 0}/l{gt}1) as {ital x} increases. These results are discussed with reference to nonlocal effects and the vortex lattice structure of the borocarbides in the mixed state. {copyright} {ital 1998} {ital The American Physical Society} |
