dc.description.abstractRoom temperature multiferroism in polycrystalline antiferromagnetic Fe-perovskites is reported for the first time. In the perovskite-type oxides RE1.2Ba1.2Ca0.6Fe3O8 (RE = Gd, Tb) the interplay of layered ordering of the Gd(Tb), Ba and Ca atoms with the ordering of the FeO4-tetrahedra (T) and FeO6-octahedra (O) results in a polar crystal structure. The layered structure consists of the stacking sequence of RE/Ca-RE/Ca-Ba-RE/Ca layers in combination with TOOT sequence in a unit cell. A polar moment of 33.0 μC/cm2 for the Gd-oxide (30.1 μC/cm2 for the Tb one) is determined from displacements of the cations, mainly Fe, and oxygen atoms along the b-axis. These oxides present antiferromagnetic ordering doubling the c-axis, the magnetic structure in the Tb-compound remains up to 690 K, which is one of the highest transition temperatures reported in Fe-perovskites.en_EN
