Title : Study of YBCO Phase Diagrams
The users oriented need for HTSC phase diagrams is discussed including the melt-textured growth, formation of glass-ceramics and conventional sintering affecting the weaks links problems. CuO -based binaries (and associated stable/ metastable compoundg) are reviewed and jointly redrawn. The ternary system Y-Ba-Cu-(0) is survayed including the effect of oxycarbonates and Pt-substitutes. The most important pseudo binary cuts are also presented. The role of oxygen pressure is shown for the disordering and superstructure formation of YBa2Cu Ox as well as for the reactions to form the other phases. In hole-doped cu prates there is now compelling evidence that inside the pseudogap phase, charge order breaks translational symmetry leading to a reconstruction of the Fermi surface. In YBa2Cu3Oy charge order emerges in two steps: a 2D order found at zero field and at high temperature inside the pseudo gap phase, and a 3D order that is superimposed below the superconducting transition Tc when superconductivity is weakened by a magnetic field. Several issues still need to be addressed such as the effect of disorder, the relationship between those charge orders and their respective impact on the Fermi surface.
