Impedance data in the range, 10-180 K fit an equivalent circuit derived from the classic dielectric relaxation circuit in which the relaxation resistance is replaced by a constant phase element (CPE). Temperature dependence of the circuit parameters shows that BZN is not ferroelectric; the CPE, which is responsible for the relaxor-like behavior, gradually changes from primarily capacitive to primarily resistive with increasing temperature. 2014-01-02T03:23:34Z 2014-01-02T03:23:34Z 2012-01 Article Journal of the American Ceramic Society, vol. 95(1), 2012, pages 296-302 0002-7820 http://onlinelibrary.wiley.com/doi/10.1111/j.1551-2916.2011.04779.x/abstract;jsessionid=31BE2529C1916CC9D075ECC2895B6093.f04t01 http://hdl.handle.net/123456789/30944 en The American Ceramic Society
