Effect of Ti4+ ions on the magnetic and dielectric properties of Mg-ferrite

Sol–gel route of synthesis of nanoparticles of MgFe2O4 and XRD, FTIR and VSM study

“…The diffraction peaks corresponding to planes (2 2 0), (3 11), (2 2 2), (4 0 0), (4 2 2), (3 3 3), (4 4 0) and (6 2 0) provide a clear evidence for the formation of spinel structure of the ferrite [14]. This observation matches well with those of earlier reporters [15,16]. It is also noted that the ferrite is free from residual a-Fe 2 O 3 phase, which is normally expected during synthesis at relatively lower temperatures.…”

Synthesis, characterization, magnetic and electrical properties of the novel conductive and magnetic Polyaniline/MgFe2O4 nanocomposite having the core–shell structure

“…Obtained 2Â peaks provide a clear evidence for the formation of single phase spinel structure of ferrite [27]. This observation matches well with those of earlier reporters [28,29], and with the ICDD card number (73-1720) used in identifying X-ray pattern, in addition to JCPDS (73-2410) file for MgFe 2 O 4 . [30][31][32].…”

Structural, electrical and magnetic characterization of Ni–Mg spinel ferrites

“…It is observed that Curie temperature decreases with the addition of non-magnetic Mg 2+ ion concentration. This expected behavior [7,14,30] is due to Mg 2+ ions having strong preference for B sites and partially occupy A site, therefore at low concentration of Mg, the net magnetization is equal to the difference between the magnetization of B and A, respectively (M AB = M B − M A ). By increasing Mg content, some of the Mg ions replace Fe 2+ ions on A sites which turn into Fe 3+ ions and migrate to the B sites.…”
