Abstract
Flux motion in anisotropic type-II superconductors near H-c2 is studie d in the framework of the time-dependent Ginburg-Landau (TDGL) theory for the case that the average flux density B is oriented in an arbitra ry direction relative to the principal axes of the sample. The lineari zed TDGL equation for a uniformly translating order parameter is softe n ann expressions for all elements of the flux-flow resistivity tensor p(ij) (including the off-diagonal Hall elements) are obtained. The di agonal elements p(ij) show the angular scaling property that rho(ij)(B ) = rho(ij)(B/H-c2(theta, phi)), whereas the Hall elements rho(ij) (i not equal j) have additional angular dependencies that are not contain ed in H-c2. For the case that the normal state Hall elements rho(ij)(( n)) proportional to B-k with i not equal j not equal k, the ratios rho (ij)/rho(ij)((n)) are functions of B/H-c2 (theta, phi) only.
