Abstract
The high- T c oxide La 2− x Ba x CuO 4 shows a local minimum in the midst of the curve of T c versus x around x ≊ 0.115, where the antiferromagnetic ordering and the structural phase transformation form the orthogonal phase to the tetragonal are reported to take place. In order to investigate the relation between these two phase transitions and the anomalous dip in T c , Zn-concentration dependence of their transition temperatures has been studied by 139La-NMR and the ultrasonic attenuation. By Zn-substitution up to 6%, the Neel temperature showed significant reduction while the structural phase transformation temperature stayed almost constant, suggesting that these two are independent of each other.
