Abstract

Dynamics of magnetic flux in quasi-one-dimensional long Josephson junctions has received an interest as a model system for soliton physics and because of possible applications for microwave generation [1]. Subjected to a sufficiently high external magnetic field H a long Josephson junction can be operated in the unidirectional flux-flow mode. Under the influence of the bias current I the solitons (magnetic flux quanta, or fluxons) are created at one boundary of the junction and annihilate at the other boundary. The soliton motion is detected by the dc voltage V measured across the Josephson junction, as a so-called flux-flow step (FFS) in the IV —characteristics.
