Abstract

Phase-pure scheelite-type solid solution SrMo1–xWxO4 oxides (x = 0.05, 0.15, 0.25, 0.4, 0.5, 0.6, 0.75, 0.85, 0.95) were synthesized by solvothermal methods and subsequently thermally treated in ammonia atmosphere at temperatures between 700 and 900 °C. As revealed by X-ray diffraction (XRD) and neutron diffraction as well as elemental analysis data, SrMo1–xWxO4 convert into their corresponding solid solution perovskite-type oxynitrides SrMo1–xWx(O, N)3 only for x ≤ 0.25 and x ≥ 0.6; whereas for 0.25 ≤ x ≤ 0.6 the formation of Sr3WO6 with double perovskite structure and of other binary oxides and nitrides was observed. The solid solution oxynitrides were investigated concerning their magnetic properties. Thus, the magnetic susceptibility of the SrMo1–xWx(O, N)3 oxynitride samples was measured by Superconducting Quantum Interference Device (SQUID). The influence of different parameters (such as phase composition, ratio between Mo and W or nitrogen content) on the magnetic behavior in the solid solution oxynitrides is briefly discussed.
