Y{sub x}Ba{sub y}Cu{sub z}O{sub 7-{delta}} ceramics forming at isobaric conditions were studied by x-ray diffraction analysis, dynamic magnetic measurements and potentiometric titration. It was established that compositions: 0.8 {le} x {le} 1.2, y=2, z=3; x=1, 1.8 {le} y {le} 2.2, z=3; x=1, y=2, 2.7 {le} z {le} 3.4: are in the homogeneity range of 123. It was found that compositions with nonstoichiometric cation ratios have minimum {Delta}T{sub c}.
