The structural and dielectric properties of lanthanum substituted strontium based spinel ferrites nano-materials for high frequency device applications

Lanthanum substitution on spinel Nano particles has a significant repercussion the several features of materials. Sol–gel (auto-ignition) allowed for rare earth lanthanum ion (La3+) ferrite with composition SrLaxFe2-xO4 (where 0.00 ≤ x 0.10). As result base’s presence, systems structural, magnetic, electrical, and magnetic properties are all modified. X-ray diffraction (XRD) assessed structural characteristics. Using diffraction, we could determine that each sample had cubic structures. Based electrical investigation, it can be concluded synthesized ferrites semiconductors, as their direct current (dc) resistivity reduces increasing temperature. The Curie temperature (Tc) was lowered from 532 K to 462 ions. values activation energy increased 0.24 eV 0.38 when is used substitute. magnetization decreased 50 27 content rose. We see gentleness material in M-H loops. All these parameters show prepared potential use high-frequency applications.
