| Phase-locking of driven vortex lattices with transverse ac-force and periodic pinning (2001) | |||||||||
Abstract | |||||||||
| For a vortex lattice moving in a periodic array we show analytically and numerically that a new type of phase locking occurs in the presence of a longitudinal dc driving force and a transverse ac driving force. This phase locking is distinct from the Shapiro step phase locking found with longitudinal ac drives. We show that an increase in critical current and a fundamental phase locked step width scale with the square of the driving ac amplitude. Our results should carry over to other systems such as vortex motion in Josephson-junction arrays.. Comment: 7 pages, 8 figures, submitted to PRB | |||||||||
