Abstract |
Normal state EPR signals have been studied for the n-type high-Tc superconductors Nd1.85Ce0.15CuO4-x and Nd2CuO3.6-xF0.4-y. Since EPR signals were observed only in quenched non-superconducting samples and were absent in furnace-cooled samples, our results suggest that no normal state EPR signals come from pure phase n-type hihg-Tc superconductors. Our observation is consistent with previously reported absence of nomal state EPR signals in the p-type high-Tc superconductors. |
