A sign reversal of magnetization is observed in Sm2CrMnO6 synthesized via the citrate-gel method. The material crystallizes in monoclinic crystal structure with P121/n1 space group. The presence of Cr3+ and Mn3+ cations is confirmed by X-ray photoelectron spectroscopy analysis. The transition temperature (TC) is found to be at 50?K from the thermomagnetic data. The magnetization reverses its sign below a particular temperature under field cooled condition and the effect is reduced and disappeared at higher applied magnetic fields. The combined interaction between different magnetic components due to the presence of Sm3+, Cr3+, and Mn3+ leads to the sign reversal of magnetization.
