Room temperature magneto-dielectric properties of PFN-CZFMO composite.

We report the structural and magneto-dielectric properties of 0.95 Pb(Fe0.5Nb0.5)-0.05 Co0.6 Zn0.4Fe1.7Mn0.3O4 (0.95PFN-0.05CZFMO, PC5) particulate composite prepared using a hybrid synthesis technique. Rietveld refinement on the XRD patterns of the end compounds i.e. PFN and CZFMO were performed using monoclinic crystal structure with space group Cm and cubic crystal structure with space group Fd-3m respectively. The dual phase space group Cm+Fd-3m was taken to refine the XRD pattern of PC5 sample which confirms the formation of composite. The changes in the dielectric parameters by the application of magnetic field suggest existence of magneto-electric coupling behavior in the composite at room temperature (RT). The quantitative changes of the magneto-dielectric properties i.e. MC% (magneto- capacitance), ML% (magneto-loss), MI% (magneto-impedance) and MP% (magneto-phase) were calculated and discussed their dependence with magnetic fields at RT.
