- Аннотация: Herein, using the systematic experimental characterization and density functional theory calculations, the effectsof Ni elemental substitution on the crystal structure, cation distribution, magnetic properties, and heat generationability of Mg1–xNixFe2O4 (x = 0, 0.2, 0.4, 0.6, 0.8, and 1) have been reported. We demonstrate that thepresence of Ni can lead the lattice shrinkage, phase transition from partially to fully inverse spinel structure, andmulti-domain structures in the samples. Moreover, Ni substitutional atoms make magnetically harder ferrite,associated with increasing magnetic inhomogeneity. Remarkably, anomalous enhancements of magnetic anisotropicand coercivity have been observed in Mg0.4Ni0.6Fe2O4. Heat generation ability (SAR) increases from 242W g 1 for x = 0–391 W g 1 for x = 0.6 at an AC magnetic field of 370 kHz frequency. Thus, the magnetichyperthermia of Mg0.4Ni0.6Fe2O4 sample on HeLa shows promising results that the viability of cells decreases to25 % after 5 sessions. The present experimental and theoretical systematic studies provide novel avenue andparadigm for the development of ferrite nanoparticles with high heat generation ability and magnetic propertiesfor biomedical applications.
