Abstract
[N (CH3)(4)][N(C2H5)(4)]CoCl4 new hybrid compound was synthesized by slow evaporation at room temperature. The X-ray powder diffraction indicates that this material has an orthorhombic structure with P2(1)2(1)2(1) space group. Two endothermic peaks at T-1 = 293 K and T-2 = 387 K are observed by differential scanning calorimetric. The real and imaginary parts of the permittivity as function of temperature shows the ferroelectric phase below T = 288 K. The Nyquist diagrams are simulated based on the equivalent circuit chosen by the Z-View-software and show the contribution of the grain and electrodes effect. Raman spectroscopy study at room temperature confirms the composition of the synthesized compound. Furthermore, the ferroelectric-paraelectric phase transition T-1 is demonstrated by temperature-dependent Raman spectroscopic studies.
