Rare earth (RE) elements lay between atomic numbers 58-71 and 90-103 in the periodic table;
namely lanthanides and actinides, respectively. They offer potential uses in the optical devices
with their optoelectronic characteristics based on their specific electron configuration. They also
have an influence on the magnetic properties of the materials they have been incorporated into.
M-type hexaferrites and spinel ferrite nano-sized materials are two of the mostly studied
magnetic nanomaterials. The magnetic, microstructural, optical, and dielectric properties of
nano-sized ferrites can be tuned by the substitution of various ions in their structure. Trivalent
RE ions, especially the non-magnetic RE3+ ions may have change the characteristics of
nanoparticles and other nano-sized materials significantly even when applied in a small amount.
In this study, we explore the partial substitution of mostly used ferrites by RE3+ prepared by
different fabrication methods such as sol-gel synthesis and sonochemical approach. The
synthesized nanoparticles have been investigated with various characterization techniques
including X-ray diffractometry (XRD), EDX-assisted scanning electron microscopy (SEM),
vibrating sample magnetometer (VSM), and diffuse reflectance spectroscopy (DRS).
