Magnetization and magnetic behavior of BixLa 1-xFeO3 ferrites

Epitaxial MgO performs a gate dielectric due to its high dielectric constant (κ = 9.8) and large band gap (Eg = 7.3eV). The MgO nanoparticle is ferromagnetic at room temperature and the magnetic phase transition is also observed. The lattice constant of bulk MgO is 4.21Å. MgO and Bi-doped MgO (Mg1-xBixO) nanoparticles will be synthesized by a hydrothermal process. The crystallinity of the nanoparticles will be analyzed in detail by ex situ XRD using Cu-Kα radiation (λ=1.5406 Å). The dielectric constant will also be estimated. The nanoparticle band gap will be measured by UV-Vis spectrometer. The surface morphology will also be imaged ex situ by an AFM. The nanoparticle size and distribution and crystallinity will be analyzed by SEM and TEM. The stoichiometry of the nanoparticles will be studied by XPS and FTIR. The magnetic properties will be performed by VSM. After synthesized, the different physical properties will be investigated by DFT
