| 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. |
