The thermal conductivity kappa of (Nd1-x-yCexSry)(2)CuO4 (NCSCO) with T*-st
ructure have been measured and compared with those of La2-xSrxCuO4 (LSCO) w
ith T-structure and of Nd2-xCexCuO4, (NCCO) with T'-structure. The phonon s
cattering mechanisms effective in NCSCO have been analyzed. (C) 2000 Elsevi
