We have studied structural, magnetic and magnetodielectric properties of polycrystalline sample α-Mn2O3 and Mn2-xVxO3 (x = 0.05). Rietveld refinement of powder x-ray diffraction data reveal the orthorhombic structure (space group Pcab) of α-Mn2O3.Vanadium doping modifies crystal structure from orthorhombic to cubic structure (space group Ia-3). The unit cell volume is found to decrease for Mn2-xVxO3 (x = 0.05). It is reported that α-Mn2O3 is a multiferroic material with an antiferromagnetic transition at ∼80K. Further, an anomaly in dielectric measurement at antiferromagnetic transition correlates to magnetodielectric coupling behavior.
