Abstract
Y-type Hexagonal ferrites have acquired much more attention due to their multiferroic qualities. The Standard formula for Y-type Hexagonal ferrites is given as (A2Me2Fe12O22) where A= Sr2+, Ba2+, Pb2+, La2+ and Me = Bivalent metal In Y-type hexagonal structure, two tetrahedral sites and four octahedral sites are inhabited with small cations. Multiferroic properties of Y-type hexaferrites can be affected by different factors such as synthesis methods, amount of substitution, sintering temperature and chemical composition. For the present study Praseodymium substituted strontium-based Y-type hexaferrites with chemical composition Sr2Ni2-xPrxFe12O22(where x=0.0 and 0.1) has been synthesized using sol-gel method and characterized byX-ray diffraction, Fourier Transform Infrared Spectroscopy and Impedance Analyzer. The structural analysis through XRD and FTIR verified the phase formation of Y-type ferrites having hexagonal structure. The XRD data reveals the increase in the volume, and decrease in particle size with praseodymium substitution. In FTIR, resulting peaks observed in two samples lie between 400-600 cm-1 which indicates the vibrational stretching in Fe-O bond.
