In this work,a novel series of multiferroic materials BiMn2O5 doped by Neodyme has been prepared by a sol-gel method at low temperature.The crystallographic studies using X-ray diffraction and Rietveld Refinement techniques showed the formation of single-phase samples for all compositions,crystallizing in a mullite-type orthorhombic perovskite structure,space group Pbam (Z =4).The SEM techniques confirmed the formation of single-phase materials with excellent mapping distribution.Raman and infrared spectroscopic measurements were performed and combined with lattice dynamics simulations to describe the room-temperature vibrational properties of all samples.The X-ray Photoelectron Spectroscopy (XPS) were measured in the energy range of 0-1400 eV at room temperature.The Fermi level EF was defined with the accuracy of 0.127,0.32 and 0.48 eV for BiMn2O5,Bi0.9Nd0.1Mn2O5 and Bi0.8Nd0.2Mn2O5 respectively.The X-ray photoelectron spectroscopy shows the existence of Mn4 + state.Magnetic measurements indicate Neél temperature TN at 31,40 and 61 K for BiMn2O5,Bi0.9Nd0.1Mn2O5 and Bi0.8Nd0.2Mn2O5 respectively.
