[en] The dielectric properties of Ba_0_._9_6Sr_0_._0_4Zr_0_._0_4Ln_xTi_0_._9_6_-_xO_3_-_δ (Ln = Y, Dy, Gd, Yb) ceramics were investigated in this work. The permittivity dependence on temperature showed the Curie temperature of the investigated ceramic samples was around 100 C. The permittivity (>10000) at room temperature is obtained when the x is 0.004 and 0.003 for Y"3"+ and Dy"3"+, respectively. The origin of the dielectric abnormality may result from the amphoteric properties of Y"3"+ and Dy"3"+. (copyright 2016 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)
