Transverse Components of Flux Line Lattice Form Factors in Uniaxial Superconductors

Magnetic field orientation dependence of transverse and longitudinal flux line lattice form factors are theoretically studied in uniaxial superconductors with extremely large anisotropy ratio 60 for some field magnitudes. The form factors are estimated by two methods, the Eilenberger theory and the London theory comparatively. We also compare them to the form factors observed by the small angle neutron scattering experiment on Sr2RuO4. We discuss the cutoff function of extended London theory, and the contributions from the suppression of the pair potential as a function of the field orientation.
