| Abstract: | The polycrystalline samples of the mixed spinel series MgCrxFe2-xO4 with x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0 have been prepared in the pellet form by standard ceramic technique and were studied by means of X-ray diffraction, magnetization and ac susceptibility measurements. The X-ray analysis shows that the samples are formed in a single-phase spinel structure. The lattice parameter a obtained from X-ray data increases initially upto x = 0.4, and thereafter it decreases. The variation of the saturation magnetic moment per formula unit measured at 300K decreases with Cr content x. The ac susceptibility was measured from room temperature to 680 K. The Curie temperature obtained from ac susceptibility measurements decreases nearly linearly with the increase of Cr content x, suggesting the decrease in ferrimagnetic behaviour. |
