On field induced diaelastic effect in a small Josephson contact

An analog of the diaelastic effect is predicted to occur in a small Josephson contact with Josephson vortices manifesting itself as magnetic field induced softening of the contact shear modulus $C(T,H)$. In addition to Fraunhofer type field oscillations, $C(T,H)$ is found to exhibit pronounced flux driven temperature oscillations near $T_C$.
