| 中文摘要 | Molecular-dynamics simulations of the current-voltage characteristics V(I) have been performed for regular arrays of asymmetric pinning centers modeled by the superposition of two interpenetrating square lattices of weak and strong pinning centers with separation Deltap. In this case, an applied Lorentz force F-L acts as a depinning force which is directed either from weak to strong pinning site or vice versa, depending on the polarity of F-L. This leads to a pronounced asymmetry of the current-voltage characteristics and of the critical currents I-c(F-L) and I-c(-F-L) ("vortex diode effect"). In addition to that, the F-L-Deltap phase diagram reveals a strong dependence of the different dynamical vortex phases on the shift between the two pinning sublattices. |
