Magnetic field 'refraction' in uniaxial type-II superconductors

The features of penetration of the magnetic field tilted at the angle γ ≠ 0 to the c-axis of the crystal are studied for uniaxial type-II superconductors with the large Ginzburg-Landau parameter. It is shown that in the fields 0<H<Hc(γ there exists a large enough interval of temperatures where the direction of the vortex lines is other than that of the field H and changes with temperature. It is noted that the magnetic flux rotation in the interval ΔT(H) leads to a temperature dependence of the elastic moduli of the vortex lattice
