Abstract content   (Max 300 words)

We report the magnetic properties of Mg_0.2Cr_1.8-xFe_xO₃ (x = 0.3, 0.5, 0.7 and 0.9) compounds. The oxides were produced by hydrothermal process and sintered at 600 ºC for 12 hours. The X-ray diffraction (XRD) data indicate single phase corundum structure in all the samples. The Mössbauer spectra recorded at about 300 K show transition from paramagnetic to ordered magnetic spin state at x = 0.5. The magnetization data reveals superparamagnetic nature of the oxides presented. The shift in hysteresis loops observed along the magnetic field axis is associated with exchange bias effect.
