The polarized x-ray Cu Kβ2,5 emission bands of Bi2Sr2CaCu2O8+x single crystals were measured. They reveal the anisotropy of the p-partial density of states (PDOS) around copper. Pure polarization components of the Cu Kβ2,5 x-ray emission band, corr

Magnetization measurements in field on a ${\mathrm{Bi}}_{2}$${\mathrm{Sr}}_{2}$${\mathrm{CaCu}}_{2}$${\mathrm{O}}_{8}$ single crystal do not reveal any sharp phase transition between the normal and superconducting states. The M(H) curves for temperat
