Abstract

We measured all nine elastic constants of a nonsuperconducting single crystal of La2CuO4 at 310, 297, and 44 K using a small-sample resonant ultrasound technique. Weak features in resonant frequencies dependent on compressional moduli were observed near 29 K, and a broad minimum occurred at 38 K, near the superconducting transition temperature of optimally doped La2CuO4. The features are also reflected in the specific heat.
