Structure lamination influence on the magnetic flux dynamics in YBa₂Cu₃O₇₋δ single crystals
Dynamics of the vortex matter in YBa₂Cu₃O₇₋δ single crystal with unidirectional twin boundaries was studied experimentally in a wide range of velocities of the magnetic flux in the tilted magnetic field. It was determined that with orientation of the magnetic field vector in the locality of ab-plane...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Dynamics of the vortex matter in YBa₂Cu₃O₇₋δ single crystal with unidirectional twin boundaries was studied experimentally in a wide range of velocities of the magnetic flux in the tilted magnetic field. It was determined that with orientation of the magnetic field vector in the locality of ab-plane, the dynamics of the magnetic flux near the melting temperature of the vortex lattice can be described by the Kim-Anderson model and under temperature lowering by the theory of collective pinning on small-scale defects or by the vortex glass model. The intrinsic pinning caused by the layered crystal structure of the material has an impact on the dynamics of magnetic flux and this effect increases with the temperature decreasing.
