✦ Synopsis

A quenching process followed by annealing in Ar atmosphere was confirmed to stabilize superconductivity in sintered Nd 1.85 Ce 0.15 CuO 4 crystals. The electrical resistivity and the thermal conductivity were examined at each stage of the heat treatments. The phonon scattering mechanisms are analyzed in a systematic way.
