The aim of this work is to study the perovskite-type oxide Ca2BWO6 materials, where B = Cr, La and Sm, obtained by the sol�gel citrate-combustion method. The nature of the B-site cations influences the structure and properties of these compound. The synthesis progress was evaluated using X-ray diffraction and the structure of the samples was characterized by the Fourier transform infrared spectroscopy. In our case, the tolerance factor decrease with increasing of the ionic radius B leads to the structural distortion different from the cubic one. The magnetic properties were evaluated by a SQUID magnetometer and they are discussed in relationship with their compositions. From experimental data, it was noticed that all compound are ferromagnetic.
