Effect of variation of facets size on fractional flux vortices at asymmetric grain boundaries in YBCO films
نویسندگان
چکیده
We consider numerically unquantized Josephson vortices at asymmetric grain boundaries in YBCO films. The study is focused on the effect of random variations of facets size on the values of fractional flux carried by these vortices. The grain boundaries are treated as Josephson junctions with a critical current density alternating along the junctions with a typical length-scale of order of the facets size. Numerical simulations demonstrate that the value of the flux of the unquantized vortices varies along the junction depending on the local Josephson properties of the grain boundaries. 2003 Elsevier Science B.V.

Nonlocal electrodynamics of Josephson junctions in thin films and fractional vortices
The phase difference φ across a Josephson junction is considered for a film with a thickness d λ, where λ is the London penetration depth in the superconducting banks. Special attention is given to the case of a critical current density jc varying along the junction. It is shown that a nonlinear integro-differential equation determines the spatial distribution of φ for d λ. Josephson properties...
متن کاملSplinter vortices at inhomogeneous asymmetric grain boundaries in YBCO films
We consider both analytically and numerically the effect of inhomogeneity of Josephson properties of grain boundaries in YBCO thin films on unquantized (splinter) vortices. It is shown that in general a smooth inhomogeneity breaks the complementarity condition /1 þ /2 1⁄4 /0 relating magnetic fluxes /1 and /2 carried by adjacent splinter vortices. 2003 Elsevier B.V.

متن کاملJosephson vortices with fractional flux quanta at YBa2Cu3O7Àx grain boundaries
We report numerical simulations of magnetic flux patterns in asymmetric 45° @001#-tilt grain boundaries in YBa2Cu3O72x superconducting films. The grain boundaries are treated as Josephson junctions with a critical current density j c(x) alternating rapidly along the junctions with a typical length scale which is much less than Josephson penetration depth. We demonstrate the existence of Josephs...
متن کاملMicrowave Frequency Power Dependence in High - Tc Thin Films , Grain Boundaries
A comprehensive study of the dc and rf electrodynamic properties of YBa 2 Cu 307-, (YBCO) thin films, grain boundaries and Josephson junctions (JJ) is presented. The surface impedance Z, = R, + iX, of YBCO thin films is shown to have a dependence on rf current, which leads to nonlinear power losses at levels of rf power that are relevant for device applications. To understand the loss mechanism...

067004-1 We have directly observed well-separated Josephson vortex splinters with unquantized magnetic flux at asymmetric 45 grain boundaries in YBa2Cu3O7 films by imaging magnetic flux with scanning SQUID microscopy. The existence of these splinter vortices has been predicted and is well described by a model based on dx2 y2 pairing symmetry and facetting of the grain boundary on a length scale...
