Abstract
The tetragonal-cubic transition was studied in Sr(Fe1/2Ta1/2)O3, together with its solid solutions with SrTiO3, Ba(Fe1/2Ta1/2)O3 and BaTiO3. At the transition temperature, the magnetic susceptibility and d.c. electrical resistivity showed small anomalies, whereas the dielectric constant did not. The tetragonal distortion in Sr(Fe1/2Ta1/2)O3 was found to be not ferroelectric but of the same type as in SrTiO3 below 110°K. The effective magnetic moment of the Fe3+ ion was found to be 5.5 µ B .Keywords
