We report on thermogravimetric, structural and magnetization measurements in the YCrO 3+γ compound obtained by the co-precipitation method. The thermogravimentric analyses show that the weight losses which occur at three distinct steps are associated with water evaporation, formation of zircon-type YCrO 4 compound and finally a phase transition from the tetragonal YCrO 4 to the orthorhombic YCrO 3 . The X-ray diffraction measurements allied with the Rietveld refinement confirm such trend, that is, the observed X-ray patterns are consistent with a gradual growth of zircon-type YCrO 4 with tetragonal structure and space group I41/amd for annealing temperatures up to 600 °C followed by the phase transition to the orthorhombic YCrO 3 phase with space group P bnm for annealing temperatures above 625 °C. The X-ray absorption near edge structure (XANES) spectra carried out in the Cr K -edge reveal that the oxidation states of Cr ions depend on the synthesis temperature. The T -dependencies of magnetic susceptibility point out a ferromagnetic-antiferromagnetic transition as function synthesis temperature. The Curie and Neel temperatures are in agreement with that reported in literature for the YCrO 4 and YCrO 3 compounds, respectively. Besides, the MvsH curves measured at 2 and 50 K are consistent with the observed magnetic states to each sample. [ABSTRACT FROM AUTHOR]
