Abstract Ferromagnetism was observed at room temperature in monodisperse CeO 2 nanospheres synthesized by hydrothermal treatment of Ce(NO 3 ) ·6H O using polyvinylpyrrolidone as a surfactant. The structure and morphology the products were characterized X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy, high-resolution field-emission scanning microscopy (FE-SEM). optical properties determined UV visible spectroscopy photoluminescence (PL). valence states Ce ions...
Abstract This work reports the study concerning structure and magnetic properties of undoped CeO 2 Fe-doped (Ce 1− x Fe O , 0.01 ≤ 0.07) nanospheres with diameters 100∼200 nm prepared by hydrothermal method using polyvinylpyrrolidone (PVP) as surfactant. The samples were studied X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), high-resolution (HRTEM), absorption near-edge (XANES), vibrating sample magnetometry (VSM). XRD results showed that was...
CoFe2O4 nanoparticles were synthesized via a co-precipitation method at pH values of 9, 11 and 14. All samples characterized using XRD, TEM, XANES VSM. The XRD results indicate pure phase cubic spinel structure They found to contain Fe2O3 impurity 9. crystallite size decreased with increased it was be in the range 41–48 nm. lattice constants also corresponding theoretical calculation. average particle sizes are 47.6–51.6 nm, which observed TEM images. valence states cation distribution Fe Co...
Nanospheres of pure CeO2 and Co-doped (Ce1−xCoxO2, 0.01 ≤ x 0.07) dilute magnetic oxide were prepared by hydrothermal treatment using cerium (III) nitrate, cobalt polyvinylpyrrolidone (PVP) as a surfactant. The samples studied x-ray diffraction (XRD), transmission electron microscopy, field-emission scanning microscopy (FE-SEM), UV-Visible spectroscopy. valence states Ce Co ions determined absorption near edge properties the vibrating sample magnetometry. results from XRD indicated that...
Structure, characterization, and magnetic properties of Ti-doped LaFeO3 (LaFe(1-x)Ti(x)O3, x = 0, 0.1, 0.2, 0.3, 0.4 0.5) nanoparticles synthesized by polymerized complex method are investigated. All LaFe(1-x)Ti(x)O3 were successfully obtained from calcination the precursor at 1050 degrees C in air for 2 h. The calcined samples characterized X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive analysis (EDX), photoelectron spectroscopy (XPS), absorption near...
