title = "Magnetic phases of Josephson vortices in Bi2Sr 2CaCu2O8+y",
abstract = "Josephson vortex (JV) states in Bi2Sr2CaCu 2O8+y (Bi-2212) have been studied by measuring the flow resistivity of JV's and I-V characteristics with a current along the c-axis. In the flow resistivity, periodic oscillations have been found as a function of the parallel magnetic field to the superconducting layers. As this phenomenon is related to the formation of a triangular lattice of JV's as the ground state, the 3D-ordered state (triangular lattice phase) of JV's could be determined. With changing the doping level of Bi-2212, the BD-ordered phase is shifted towards a higher magnetic field and a higher temperature, which is well explained from the theoretical analyses. Above the 3D-ordered phase, vortex state has been studied with I-V characteristic measurements, in which the voltage shows a distinct change in the exponent of the power-law dependence to the current between two phases. This suggests that the 3D-ordered phase changes to the disordered phase along the c-axis.",
