摘要：

Near 70K (La,Ba)2CuO4 undergoes a structural transition from orthorhombic to tetragonal symmetry (LTO-->LTT). Partial substitution of La by Nd produces an additional transition that has been observed in structural studies. The specific heats of La1.475Nd0.4Sr0.125CuO4 and La1.275Nd0.6Sr0.125CuO4 samples exhibit anomalies near 75K, which are associated with these structural transitions, and additional smaller anomalies near 30K, which may be associated with a magnetic transition detected by muSR.
