Abstract
The deviations of experimental results for torque in YBa2Cu3O7 at high angles from predictions of the anisotropic Ginzburg-Landau model are explained in the framework of the Lowrence-Doniach model taking into account the two-dimensional pancake structure of the normal cores of the vortices. Measurements of the torque at high angles allows us to obtain the core energy of the vortex and the parameter that characterizes the interlayer coupling.
