Abstract
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 TC.
