An insight into the nanosize and bulk Ni0.5Co0.5Fe2O4 ferrites through their comparative study: Structural and magnetic investigations

Analysis of Raman, Mossbauer Spectra and Dielectric Behaviour of Sol-Gel Prepared Ni1-xCoxFe2O4 Spinel Ferrites

“…16 S. Joshi et al reported Fe +3 peaks for octahedral and tetrahedral sites at 709 eV and 711 eV respectively for Ni 0.5 Co 0.5 Fe 2 O 4 ferrite. 18 The peaks at 710.2 eV and 712.2 eV for Fe 2p 3/2 XPS spectra of Ni 0.5 Co 0.5 Fe 2 O 4 observed by MU Sawal et al 32 confirmed the Fe +3 state of B and A sites respectively. The peaks at 709.1 eV and 711.3 eV for Fe 2p 3/2 XPS spectra of Ni 0.5 Co 0.5 Fe 2 O 4 observed by SR Gibin et al 33 were assigned to B and A sites respectively.…”

“…The peak positions for the elements i) O 1s at 529 eV, Fe 2p at 710 eV, Co 2p at 780 eV and Ni 2p at 854 eV in the survey spectrum are matching with earlier reports. 22,32 The graph of Fe 2p has two peaks around 710 and 723 eV for 2p 3/2 and 2p 1/2 orbitals respectively. The fitting of these two peaks after deconvolution confirms the presence of Fe +3 states.…”

Synthesis of Ni0.5Co0.5Fe2O4 Ferrite and Effect of Annealing Temperature on the Structural, Morphological and Dielectric Analysis

“…Kumar et al (20) investigated the structural and dielectric properties of NPs of Co(0.5x)NixZn0.5Fe2O4 (x = 0 to 0.3) as prepared by the co-precipitation method. Sawal et al (21) proposed research work that manifests the comparison of nanosized 'as prepared' Ni0.5Co0.5Fe2O4 ferrite with their 'sintered' counterpart concerning their effect on the structural and magnetic properties. Various researchers have reported their work on the specific stoichiometric Ni0.5Co0.5Fe2O4 NPs using multiple dry and wet chemical synthesis methods and the temperature variation concerning different sintered samples.…”
