In this work, Sr0.3Ba0.4Pb0.3Fe12O19/(CuFe2O4)x (x = 2, 3, 4, and 5) as strongly exchange-coupled nanosized ferrites were fabricated using a one-pot sol–gel combustion method (citrate sol-gel method). The X-ray diffraction (XRD) powder patterns of the products confirmed occurrence pure, ferrites. Frequency dependencies microwave characteristics (MW) investigated co-axial method. non-linear behavior MW with composition transformation may be due to different degrees Fe ion oxidation on...
Abstract Indium-substituted strontium hexaferrites were prepared by the conventional solid-phase reaction method. Neutron diffraction patterns obtained at room temperature and analyzed using Rietveld methods. A linear dependence of unit cell parameters is found. In 3+ cations are located mainly in octahedral positions 4f VI 12 k. The average crystallite size varies within 0.84–0.65 μm. With increasing substitution, T C Curie decreases monotonically down to ~ 520 K. ZFC FC measurements showed...
Abstract Exchange‐coupled hard–soft bi‐magnetic ferrites can be used as isolators, microwave absorption materials, filters, hyperthermia and biosensors with improved energy properties. The nanocomposites the chemical composition SrIn x Fe 12‐ O 4 /Ni 0.5 Zn 05 2 (where varies from 0.00 to 0.04) have advantages of both materials: spinel hexaferrite. combination Sr‐hexaferrate ferrite results in proximity effects, reversal magnetization two stages, blocking temperatures that tuned hard soft...
ABSTRACT Double perovskite oxides (POs) are effective electrode materials for supercapacitors (SCs). Nevertheless, adapting their unique architectures to boost the electrochemical performance remains tricky. Herein, we present exceptional La 2 MnXO 6 (X = Co, Fe) double perovskites as SC materials. The sol–gel method has prepared MnCoO (LMCO) and MnFeO (LMFO) nanorods. XRD revealed that LMCO LMFO have monoclinic crystal structures with lattice constants of a 5.517 Å, b 5.528 c 7.805 β...
Co-Tm nano-spinel ferrite with chemical formula CoTmxFe2-xO4 (0.0 ≤ x 0.08) NPs were prepared via sonochemical approach. X-ray powder diffraction patterns, microscopic images (SEM and TEM) infrared spectra proved the formation of Co spinel ferrite. The effect Tm3+ substituted on spinal structure was evaluated by lattice parameters, tetrahedral octahedral bond length cationic distribution. band gap energy (Eg) samples estimated performing UV-Vis percent diffuse reflectance (% DR) applying...
Nanoparticles (NPs) of composition Co0.3Ni0.5Mn0.2EuxFe2-xO4, where 0.00 ≤ x 0.10 (hereafter called CNMEuF) were synthesized by sonochemical approach using UZ SONOPULS HD 2070 ultrasonic homogenizer (frequency 20 kHz and power 70 W). As-synthesized samples characterized thoroughly to determine the effects europium ions (Eu3+) substitution on their structure, morphology magnetic traits. Structural analyses NPs confirmed high purity crystalline cubic phases. Percent diffuse reflectance (%DR)...
This paper reports the synthesis, structural characteristics and magnetism of SrFe12O19/MCe0.04Fe1.96O4 (M = Cu, Ni, Mn, Co Zn) hard/soft nanocomposites. The compositions were manufactured via a one-pot reactions citrate sol-gel approach. phases formation was confirmed using XRD, SEM, TEM HRTEM techniques.

Green and facile process for Ni0.4Cu0.2Zn0.4Fe2−xEuxO4 (x = 0.00–0.10) spinel ferrite nanoparticles (SNPs) prepared via ultrasonic irradiation (without any post annealing process) has been deeply investigated. The influence of Eu3+ substitutions on the structure, morphological, optical, magnetic, electrical dielectric traits NiCuZn SNPs was assessed. Tauc plots revealed direct optical band gaps in a very tight interval 1.86–1.90 eV. Magnetization measurements exposed superparamagnetic...
