The polycrystalline SmMn1.8B0.2O5 (B = Fe, Cr, Co, and Ni) have been synthesized by using the sol-gel auto combustion technique sintered at 9500C. The samples are characterized by X-ray diffraction at room temperature which shows that all the samples are single phase because no secondary peaks were observed in the process of fitting by JANA 2006. All materials have an orthorhombic structure with a space group of Pbam. By changing the elements of the B-site with the same proportion, the variation in the lattice parameters and volume is described briefly and compared with other RMn2O5 multiferroics. The temperature-dependent electrical measurements were performed to calculate the activation energy and Arrhenius plot which show that all materials have semiconducting nature.
