Because of its broad range of functional applications,
numerous kinds of perovskite-structured ceramics
have been widely studied. However, the properties
of barium iron tantalate, Ba(Fe1/2Ta1/2)O3 (BFT),
which has a perovskite structure is not well known
and only few studies have been performed. In the late
1950s, Galasso et al. [1] reported that the crystal
structure of BFT is cubic perovskite and the lattice
parameter is about a = 4.056A ° .An interesting phenomenon
quoted in the paper is that the BFT showed
