THE HIGH QUALITY N-TYPE SUPERCONDUCTOR OF Nd1.85Ce0.15CuO4-y PREPARED BY HOT PRESSING

Since the discovery of high T_c copper oxide superconductor by J. G. Bednorz and K. A. Müller, several kinds of copper-based oxide superconducting system have been reported, such as YBaCuO, BiSrCaCuO and TlBaCaCuO. Their Hall coefficients and thermopower measurements demonstrated that they are hole-...

Zusammenfassung:Since the discovery of high T_c copper oxide superconductor by J. G. Bednorz and K. A. Müller, several kinds of copper-based oxide superconducting system have been reported, such as YBaCuO, BiSrCaCuO and TlBaCaCuO. Their Hall coefficients and thermopower measurements demonstrated that they are hole-like superconductors. Because of the high T_c
