Abstract
In the present study, site occupancy of Dysprosium(Dy), Samarium(Sm) doped Magnesium ferrite were investigated by electro paramagnetic resonance (EPR). Point charge calculations were used to predict the EPR spectrum of each lanthanide in A- and B-sites. Different EPR spectra are expected for A- versus B-site substitution when Sm3+ and Dy3+are the dopants. The experimentally observed doping behavior of Dy3+ –Sm3+ in MgFe2O4 suggests that as a Sm3+ cation it is on the A-site. EPR signal intensity suggested the amphoteric behavior due to Dy3+ in the magnesium ferrite material as Dy3+ was found to be a B-site dopant. These studies will be helpful for the analytical studies of permittivity and permeability to design Microstrip patch antenna to be used in pervasive computing.
