Study on some Superconductor Materials

In particular, there are extensive measurements have been made using IGA technique to measure the change in the oxygenstoichiometry x, as a function of pressure and temperature at equilibrium condition. Since the chemical potential ?, is sensitive to the oxygen stoichiometry x, the measurement technique allows to extract the thermodynamic response function 2k(?x???)T whiSubstitution the yttrium ion Y, in the superconductor compound Y1Ba2Cu3O6+x by other rare earth ions Re=Er, strongly expected varies with change in the ion size due to the changes in the lattice parameter. These changes may or may not make in oxygen conteIt is important to compare our phase diagram with the best other reported experimental works and fit them to Salford-theoretical model. The phase equilibrium diagrams is quite useful to understand the conditions necessary for processing high temperature s
