文摘

Recently, the crossing vortex lattice state in highly layered superconductors such as Bi₂Sr₂CaCu₂O_8+δ has been explored both theoretically and experimentally by intensive studies in magnetic fields parallel to the superconducting CuO₂ plane. We discuss to establish the vortex phase diagram obtained by the novel ac-miniature coil measurement with emphasis on the spatial symmetry breaking.
