Abstract

A series of praseodymium-doped Zn0.5Mg0.5PrxFe2-xO4 (x= 0.0, 0.02, 0.06 and 0.10) ferrites were synthesized by solid-state reaction method to study the impact of doping Pr3+ ions on the structural and magnetic properties of Zn0.5Mg0.5PrxFe2-xO4 ferrite compositions. The powdered x-ray diffraction studies revealed the presence of peaks corresponding to tetrahedral and octahedral positions, confirming cubic spinel structure in all samples. Vibratory sample magnetometer study revealed changes in microscopic magnetic properties. The net magnetization increased while the coercivity decreased with increase in concentration of Pr3+ substitution. 57Fe Mössbauer studies were used to obtain the chemical state of iron and its occupancy to tetrahedral/octahedral site and to estimate the cation distribution of tetrahedral site and octahedral site in all synthesized ferrite compositions. Using the cation distribution of tetrahedral site and octahedral site, an attempt is made to understand the magnetic properties of Pr doped Zn-Mg ferrites.
