Synthesis, characterization and evaluations of structural, morphological and magnetic studies of yttrium doped Ni-Zn nano-ferrites via sol-gel method

Abstract

The yttrium-doped Ni-Zn ferrite of Ni0.4Zn0.6YxFe2−xO4 (x = 0.0, 0.03, 0.06, 0.09 and 0.12) nanoparticles was routed through sol-gel to examine the structural and magnetic. XRD authorized the establishment of a single-phase spinal structure and it was noticed that crystallite size (20.14 nm – 35.18 nm), lattice constant (8.369 ˚A – 8.424 ˚A), jump lengths (LA is from 3.635 ˚A – 3.651 ˚A and LB is from 2.963 ˚A – 2.976 ˚A) and unit cell volume (591.86 ˚A3 to 599.29 ˚A3) were increased with yttrium substitution. The density and porosity of the samples considerably varied with yttrium substitution. FESEM confirmed the morphology of the samples and EDX spectrographs were estimated the elemental compositions. The saturation magnetization (29.19 − 19.89 emu/g), remanence (16.79 − 11.63 emu/g), coercivity (206 – 56 Oe) and magnetic moment (1.24 – 0.86 A-m2) were maintained the decrease trend with yttrium substitution.
