Transport Properties and Upper Critical Field of Single Crystal Non-Magnetic LuxY1-xNi2B2C and Magnetic LuxGd1-xNi2B2C Conference Paper uri icon

abstract

  • The in-plane resistance of single crystal non-magnetic Lu x Y 1-x Ni 2 B 2 C and magnetic Lu x Gd 1-x Ni 2 B 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 Hc2(T) is anisotropic for both. A positive curvature in Hc2(T) near Tc(x) is clearly observed only for the non-magnetic impurity. At low temperature Hc2(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 x Gd 1-x Ni 2 B 2 C .
