Abstract
The structural transition to a low-temperature tetragonal phase in La2 -xBaxCuO4 occurs at the hole concentration p approximately 1/8. We hav e studied the structural and electrical properties of La2-y-xNdyBaxCuO 4 with x = 0.125 to clarify the effect of substitution by trivalent io ns. The substitution by Nd3+ enhances the structural transition temper ature without changing of p. This enhancement is qualitatively explain ed by the crystallochemical origin.
