The phase \(\mathrm{YSr}_{2} \mathrm{Cu}_{2} \mathrm{CoO}_{7}\) (orthorhombic, \(/ \mathrm{ma}^{2}\) ) is structurally related to \(\mathrm{YSr}_{2} \mathrm{Cu}_{2} \mathrm{GaO}_{7}\), but has a component of disorder associated with the oxygen sublattice. Substitutions of small amounts of Ba for \(\
Temperature dependence of the nuclear relaxation rate of both Cu(1) and Cu(2) sites indicates the appearance of the magnetic order without destroying superconductivity in the Fe-doped YBa2Cu307. The impuity-induced antiferromagnetism of Cu moments is verified also by the observation of ~he antiferro
