摘要
A standardized slow evaporation growth procedure was used to successfully cultivate the black-coloured crystalline form of PMPMCM. The orthorhombic system with space group Pna2₁ is where the PMPMCM crystallises. The dielectric Permittivity of PMPMCM was calculated within the heat range of 30 to 110 °C. PMPMCM’s piezoelectric characteristics were investigated under typical lab settings and the obtained d33 coefficient value is 19.64 pC/N. A notable internal bias field within PMPMCM is indicated by characteristic features in the P-E loops and residual polarisation (Pr) of 0.91 µC/cm2. To find the pyroelectric coefficient, pyroelectric investigations on PMPMCM were conducted. The DC conductivity of PMPMCM was examined in relation to temperature, and a steady rise in conductivity was noted. The PMPMCM crystal has a cut-off wavelength of 230 nm and is optically clear throughout the visible spectrum, with a transmittance of 62%. The laser-induced surface damage threshold of PMPMCM was found to be 1.4744 GW cm⁻2 when exposed to a 1064 nm Nd:YAG laser. Based on particle size-based SHG analysis, PMPMCM shows a phase matchable nonlinear optical response. With nonzero coercivity (Hc) and remanent magnetisation (Mr), the PMPMCM magnetisation curve clearly displays ferromagnetic hysteretic behaviour.
