摘要：
The ac electrical properties of lead chloride single crystal (PbCl2) were investigated at room temperature in the frequency range 1 Hz to 10(6) Hz. The real and imaginary components of permittivity and modulus were determined from ac measurements. The results indicate that the bulk material of PbCL(2) single crystal can be represented by parallel RC circuit. The spectrum of the plot of the imaginary components of the impedance Z '' and electric modulus M '' versus frequency yield a broad Debye peak indicating overlapped relaxation transition processes (polar and structure).
