Popis:	Coexistence of both sharp transition around (Tc1 ∼ 305 k) in lower frequency region (∼11 kHz) and broad transitions (∼350 P m 3 ¯ m at room temperature (30 °C) as is clear by X-ray diffraction and rietveld analysis. An analysis of real and imaginary part of dielectric permittivity and electric modulus with frequency at various temperatures has been performed. Using Cole–Cole model, an analysis of the imaginary part of the dielectric permittivity with frequency is performed using a distribution of relaxation times.
