Transport Properties and Upper Critical Field of Single Crystal Non-Magnetic Lu[sub x]Y[sub 1-x]Ni[sub 2]B[sub 2]C and Magnetic Lu[sub x]Gd[sub 1-x]Ni[sub 2]B[sub 2]C.

The in-plane resistance of single crystal non-magnetic Lu[sub x]Y[sub 1-x]Ni[sub 2]B[sub 2]C and magnetic Lu[sub x]Gd[sub 1-x]Ni[sub 2]B[sub 2]C samples as a function of the magnitude and direction of the magnetic field and temperature have been measured. The superconducting upper critical field H[sub c2](T) is anisotropic for both. A positive curvature in H[sub c2](T) near T[sub c](x) is clearly observed only for the non-magnetic impurity. At low temperature H[sub c2](T) for the sample with magnetic impurities is strongly reduced. Thermopower, thermal conductivity and resistivity as a function of temperature are also reported for Lu[sub x]Gd[sub 1-x]Ni[sub 2]B[sub 2]C. [ABSTRACT FROM AUTHOR]
