Abstract

Using Ginzburg-Landau theory within a tensor-effective-mass approximation, we calculate the angular dependence of the shear moduli of uniaxial superconductors such as the high-temperature superconductors. When expressed as a function of the reduced magnetic field, our results are consistent with those using a London approximation at zero wave vector. Our calculations are generalized to finite wave vector, and also suggest that shear-modulus renormalization is universal for arbitrary magnetic fields, in the large κ limit.
