Abstract
The transition temperature to the low-temperature tetragonal structure T-d2 has been investigated for La1.875Ba0.125Cu1-yZnyO4 It has been r evealed that T-d2 is almost constant at least up to Zn content of y=0. 06. The low-temperature tetragonal structure is neither enhanced nor s uppressed by a small amount of Zn doping for the Cu site. This is in c ontrast to the structural transition at higher temperature, which is e nhanced by the Zn doping.
