TORQUE PROPERTIES OF THE ORTHOGONAL FLUX-LINE CONFIGURATION

We consider extremely type-II uniaxial superconductors in the context of anisotropic London theory and study the high vortex density limit w hen the magnetic induction is tilted with respect to the axis of symme try. We obtain some further properties of the vortex-flux arrangement recently considered by Preosti and Muzikar - two sets of orthogonal li nes, along and perpendicular to the c-axis. We obtain the critical lin e in the diagram of anisotropy, gamma, versus the Ginzburg-Landau cons tant, kappa, below which such decomposition may occur. In the reversib le region of the H-T diagram we propose a method, based on torque and magnetization experiments, to check the existence of this orthogonal s tate.
