Crystal structure and phase transitions of Sr2Ni1–yMgyMoO6 solid solutions

详细

Sr₂Ni_1–yMg_yMoO₆ mixed oxides with a double perovskite structure have been synthesized via the pyrolysis of glycerol–salt mixtures. The phase composition and structure of the samples have been determined using X-ray diffraction and Raman spectroscopy. The temperatures of phase transitions in Sr₂Ni_1–yMg_yMoO₆ with y = 0.25, 0.5, and 0.75 have been determined by high-temperature X-ray diffraction and dilatometry.
