Note that in our case the nonlocal tilt modulus c 44 (k z ) is identical to compression modulus c 11 (k z ) and they coincide with elastic moduli within the anisotropic London model (61) and (62) in the limitk z λ ab ≫ 1, k x λ z . This elastic energies (74), (75), and (76) can be used to study weak fluctuations and weak pinning of the dense Josephson vortex lattice.…”

Many superconducting materials are composed of weakly coupled conducting layers. Such a layered structure has a very strong influence on the properties of vortex matter in a magnetic field. This review focuses on the properties of the Josephson vortex lattice generated by the magnetic field applied in the layers direction. The theoretical description is based on the Lawrence-Doniach model in the London limit which takes into account only the phase degree of freedom of the superconducting order parameter. In spite of its simplicity, this model leads to an amazingly rich set of phenomena. We review in details the structure of an isolated vortex line as well as various properties of the vortex lattice, both in dilute and dense limits. In particular, we present an extensive consideration on the influence of the layered structure and thermal fluctuations on the selection of lattice configurations at different magnetic fields.Comment: 27 pages, 19 figures, to be published in the memorial issue of JETP devoted to A.

“…Because of the very large / > 10 4 [41,42] and the evidence that these materials are A c c e p t e d M a n u s c r i p t 12 strongly layered [13,17,57], we have chosen to set aside the anisotropic mass description for the angular dependence of resistivity and consider these Bi-based materials as consisting of highly conductive -layers separated by highly resistive layers. This leads to an angular dependence for the resistivity given by [58] N ( ) = cos 2 + sin 2 .…”

AbstractThe detrimental effects of grain boundaries have long been considered responsible for the low critical current densities ( c ) in high temperature superconductors. In this paper, we apply the quantitative approach used to identify the cause of the 'weak-link' grain boundary behaviour in YBa2Cu3O7 [1], to the Bi2Sr2CaCu2O8 and Bi2Sr2Ca2Cu3O10 materials that we have fabricated. Magnetic and transport measurements are used to characterise the grain and grain boundary properties of micro-and nanocrystalline material. Magnetisation measurements on all nanocrystalline materials show non-Bean-like behaviour and are consistent with sur...

“…As the field decreases, such an aligned vortex lattice becomes unstable owing to the shear instability [1], and the shearing angle of vortex lattices increases continuously [2]. As the field further decreases, the rotated vortex lattices have been considered to be the ground state [3,4,5]. The studies mentioned above (except for Ref.…”

Energy landscape and shear modulus of interlayer Josephson vortex systems

The ground state of interlayer Josephson vortex systems is investigated on the basis of a simplified Lawrence-Doniach model in which spatial dependence of the gauge field and the amplitude of superconducting order parameter is not taken into account. Energy landscape is drawn with respect to the in-plane field, the period of insulating layers including Josephson vortices, and the shift from the aligned vortex lattice. The energy landscape has a multi-valley structure and ground-state configurations correspond to bifurcation points of the valleys. In the high-field region, the shear modulus becomes independent of field and its anisotropy dependence is given by c66 ∝ γ −4 .
