In this work we provide the report on the preparation of a bulknhyphen;type NdCeCuO superconductor using a highhyphen;pressure highhyphen;temperature sintering procedure. The superconductor was obtained by sintering ashyphen;prepared material at 4.0 GPa at 530thinsp;deg;C for 20 min and required no additional reducing treating. The sample shows a higher onset temperatureTcon(32 K), a higher zero resistance temperatureTc0(22 K), and a much lower resistivity than a standard bulk sample. Indeed the roomhyphen;temperature resistivity and the quasimetallic resistivity in the normal state for our polycrystalline sample are similar to those of single crystals. This highhyphen;pressure sintering procedure reduces weak link effects and opens the possibility of preparing highhyphen;quality bulknhyphen;type superconductors.
