OSTI ID:5574064
The effect of magnetic impurities on the high T/sub c/ superconductor La/sub 1.85/Sr/sub .15/CuO/sub 4/ was investigated by replacing La with Nd. We find a depression of T/sub c/ and dH/sub c2/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. 8 refs., 2 figs.
