Abstract: The structural and magnetic properties of mixed spinel system Mn1+xSixFe1-xCr1-xO4 (x = 0.0, 0.1,0.2,0.3,0.4,0.5) have been investigated by X-ray diffraction and magnetization studies. X-ray intensity calculations indicate that Si4+ ions occupy only tetrahedral (A) sites replacing Fe3+ ions and Mn3+ ions replace Fe3+ ions from (B) site. The variation of saturation magnetic moment per formula unit measured at 300 K with the Si4+ content is explained on the basis of Neel’s collinear spin ordering model.
