Transition Metal and Rare Earth Doped CuFe2O4 nanoparticles

CuFe2O4 ferrite doped with rare earth (Eu3+) and transition metal (Sc3+) ions has been studied for its structural, dielectric, magnetic, and humidity-sensing capabilities. Glucose and urea were used as fuel in a solution combustion process. X-ray diffraction (XRD) and scanning electron microscopy (SEM) was used to study the samples' structure and microstructure. Electrical, magnetic, and humidity sensing capabilities have been studied using impedance analyzers, superconducting quantum interference devices (SQUIDs), and humidity sensors.
