Structure and humidity sensitive electrical properties of the Sn4+ and/or Mo6+ substituted Mg ferrite

Effect of In3+ ions doping on the structural and magnetic properties of Mg0.2Mn0.5Ni0.3InxFe2−xO4 spinel ferrites

“…Formation of second phase has also been reported when rare earth metal cations were substituted in MnZn ferrites [31]. A nonlinear change of lattice constant 'a' with concentration in spinel ferrites has also been reported earlier [32,33]. Probability that indium ions occupy tetrahedral A-sites for x40.1 may be very remote.…”

Effect of Tb substitution on structural, magnetic and electrical properties of magnesium ferrites

“…The appearance of secondary phase on the grain boundaries may suppress the grain growth by limiting the grain boundary mobility [13]. A nonlinear change of lattice constant 'a' with concentration in spinel ferrites has also been reported earlier [14]. The Tb 3+ ions may reside on B-sites as Tb 3+ ions have larger ionic radius (0.93 Å ) as compare to that of Fe 3+ (0.64 Å ) ions.…”

Microwave assisted synthesis and characterization of Co doped Cu ferrite nanoparticles

“…The ferrite nanoparticles are having large number of applications in different areas such as biomedical, ferrofluid, magnetic media, microwave, magnetocaloric refrigeration, gas sensors etc. [1][2][3][4][5][6][7][8][9][10][11][12][13]. Various parameters play an important role in determining the properties of the material for a particular application.…”
