The superconducting properties of YBa2Cu307-x have been shown to depend markedly on the overall oxygen stoichiometry and on the ordering of oxygen vacancies on the available sites. YBa2Cu307\_ x has been studied in situ by high-temperature neutron powder diffraction in controlled oxygen atmospheres
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
