Abstract

Ultrasonic and specific-heat measurements have been performed across the superconducting transition on a single crystal of La1.86Sr0.14CuO4. A pronounced jump of the elastic constant ΔC33(Tc) = -0.15 GPa is observed at Tc = 34 K as well as a specific-heat jump Δcp/Tc = 9.6 mJ/K2mol, whereas a jump in C11 is less obvious. The results allow quantitative estimation of the strain dependence of Tc and the condensation energy along the a and c axes.
