Abstract
Resistive measurement of superconducting transitions under externally applied magnetic fields in polycrystalline samples of YPd5B3C0.3 and YNi2B2C has revealed a marked positive curvature in the temperature dependence of Hc2, with the slope - dHc2/dT increasing monotonically from Tc to 4.2 K. This observed positive curvature is in marked contrast with the predictions of the conventional theories of upper critical field. It is possible that a compensation mechanism may have to be invoked to account for the observed results.
