摘要：

AFe(1/2)B(1/2)O(3)(A=Ba, Sr, Ca; B=Nb, Ta, Sb) ceramics were synthesized and temperature dependences of dielectric permittivity were measured at different frequencies. The experimental data obtained show very high values of dielectric permittivity in a wide temperature interval that is inherent to so-called high-k materials. Analyses of these data establish a Maxwell-Wagner mechanism as a main source for the phenomenon observed. (C) 2003 American Institute of Physics.
