چکیده انگلیسی مقاله In the present study, erbium-doped nickel ferrites, Ni0.5Sr0.5ErxFe2-xO4 (x=0.003+ ions successfully doped into the spinel lattice of Ni0.5Sr0.5ErxFe2-xO4 without any distortion. The influence of Er3+ ions on the structure, surface morphology, and magnetic behaviour has been determined by powder XRD, EF-SEM, DSC-TGA, VSM, etc., and PXRD confirmed the spinel nanocrystalline structure. SEM analysis showed the size is between 27-30 nm with irregular morphology and grain boundaries. EDAX confirms elements in the expected percentage. The weight loss due to the degradation of synthesised nanoparticles (NPs) was studied by TGA-DSC. VSM at room temperature confirms the cubic spinel structure and soft magnetic in nature and can be altered with a variation of Er3+ ions. The glassy carbon electrode (GCE) was modified by coating a layer of synthesized Ni0.5Sr0.5ErxFe2-xO4 to detect the electron transfer reactions using cyclic voltammetry and also to sense the presence of Hg2+ in the polluted sample.
