In this work, CaFe2O4 is successfully synthesized with a natural source of precursors by the milling method. The X‐ray diffraction confirms the orthorhombic CaFe2O4 compound. Scanning electron microscopy shows agglomerated porous crystalline type morphology. Photoluminescence spectra show that CaFe2O4 absorbs visible regain at wavelength 584 nm. The synthesized CaFe2O4 compound shows p‐type gas sensing...
Preparation of Ni‐Mg‐Zn‐Co ferrites having general formula Ni0.5‐x Mgx‐0.01 Zn0.5‐y Coy+0.01 Fe2O4 (where x = 0.1, 0.2, 0.3, 0.4 and y = 0.1, 0.2, 0.3, 0.4) is carried out by conventional ceramic method. The X‐ray diffraction studies of compositions reveal the formation of single‐phase cubic spinel. The lattice parameter “a,” bond lengths RA, RB, and site radii rA, rB are found to increase linearly...
