Abstract

The longitudinal elastic constants in high-quality single crystals La_1.86Sr_0.14CuO₄ were measured across the superconducting transition temperature T_c under magnetic fields up to 14T applied both parallel and normal to the CuO₂-plane. We found anomalies of elastic constants at T_c, indicating the anisotropic coupling between the high- T_c superconductivity and lattice. We newly found anomalies below 4K under high field, suggesting the field induced instability of the lattice.
