摘要：

Electrically equivalent circuits for the paraelectric phase of layer-structured BaBi4Ti4O15 single crystals in the parallel and perpendicular directions to the (Bi2O2)(2+) layer were identified by complex impedance and modulus analysis at 600 to 767 degrees C. The same form of single semicircle in complex impedance plots for both directions could be differentiated by using complex modulus plots. The equivalent circuits for the parallel and perpendicular directions to the (Bi2O2)(2+) layer were identified as a single parallel RC circuit and two parallel RC circuits in a series array, respectively.
