Quantum vortex creep: Hall and dissipative tunneling

Within the framework of the path-integral approach, we study the quantum vortex creep for the situation where both the Hall and the dissipative dynamics are simultaneously present. We calculate the relaxation rate and the crossover temperature separating the thermal activation and the quantum tunneling processes for anisotropic or multilayer superconductors. The results are compared with the available experimental data. (C) 1998 Elsevier Science B.V. All rights reserved.
