عنوان انگلیسی Scanning Hall Probe Microscopy (SHPM) Measurements of Crossing Vortex Lattices in (BSCCO) (2212 ) Single Crystals under Very High-Plan Fields
چکیده انگلیسی مقاله Semiconductor 2DEG with scanning hall probe microscopy Probe devices technique have been employed in the Bi2Sr2CaCu2O8+δ superconductor to explore for new phases of vortex matter in single crystals. Josephson vortices (JVs) and pancake vortices (PVs) are two orthogonal forms of flux structures that are created in the crossing lattices regime of these highly anisotropic superconductors when the magnetic fields are slanted (JVs and PVs). Studying the interaction of JV-PV material with extremely high in-plane fields has been done using SHPM technology. As a result of both in plane and out of plane fields, the spacing of JV chains has been measured. A surprising discovery is that the JV chain spacing is not simply dependent on the in plane field, as determined reliably, and that the functional anisotropic, , γ_eff, is highly dependent on the out of plane field strength. Furthermore, the Josephson vortices stack spacing displays noticeable sawtooth-like oscillations as a function of the out of plane field while the in plane field is fixed. In extremely anisotropy cuprate superconductors with large Josephson vortex stack densities, these observations are revealing previously unknown features of crossing vortex lattics.
