Synthesis and investigation of structural, morphological, thermal behaviour, and magnetic properties of CoFe2O4-MnO2 nano-composites

High-performance microwave absorption by optimizing hydrothermal synthesis of BaFe12O19@MnO2 core–shell composites

“…Magnetic saturation and coercivity can decrease with an increasing MnO 2 fraction. Past research works 57–59 emphasized that because MnO 2 is antiferromagnetic, its spin results in a decrease in surface anisotropy, reducing the spin magnetic moment. The remanence increased with the MnO 2 fraction, which was possible because Fe 3+ ions occupy BHF crystals in the octahedral, tetrahedral, and trigonal bipyramidal lattices.…”

Statistically Analyzed Heavy Metal Removal Efficiency of Silica-Coated Cu0.50Mg0.50Fe2O4 Magnetic Adsorbent for Wastewater Treatment

“…39 A band at 1620 cm −1 , demonstrating H−O−H bending vibrations, appeared due to water molecules present in the silica-coated spinel ferrite and a band witnessed at 1680 cm −1 revealed OH stretching associated with hydrogen bonding, which arises from manganite. 40 Relatively weak vibration bands at 2352 and 2920 cm −1 were referred to CO 2 and C−H stretching vibrations. 41 Measurement of the magnetic properties of materials is commonly accomplished by performing VSM analysis.…”
