Abstract

The temperature dependence of the thermal expansion, the dielectric constant, the pyroelectric current and the remanent polarization in polycrystalline samples of Ba(Ti1-xSnx)O3 was measured. The influence of the external electric field and Sn-substitution on the character of all phase transitions was investigated.
