NMR Line Shape in Anisotropic Superconductors in Inclined Magnetic Fields.

摘要

The nuclear magnetic resonance line shapes within a primitive cell of the vortex lattice of the type II anisotropic superconductors in inclined magnetic fields are constructed taking into account a change of the local magnetic field inhomogeneity and skin - effect near the superconductor surface. The results of the numerical calculations show that the change of the direction of an external magnetic field modifies the parameters of the nuclear magnetic resonance line shapes. The derivative of the power of the absorption energy with respect to the magnetic field is calculated. It allows to obtain more detailed information about parameters of the superconductor such as an anisotropy parameter.
