The effect of magnetic impurities on the high Tc superconductor La1.85Sr.15CuO4 was investigated by replacing La with Nd. We find a depression of Tc and dHc2/dT with increasing Nd concentration which does not follow predictions of the pairbreaking effects due to magnetic impurities. We attribute our experimental results to a density of states effect.
