Study of magnetic spiral in the room temperature multiferroic BiFeO3 - PbTiO3

BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature...铁酸铋（BiFeO₃）是一种室温多铁性材料，同时具备铁电性与反铁磁（antiferromagnetic, AFE）有序特性。x-铁酸铋-（1-x）-钛酸铅（x-BiFeO₃ - (1-x)-PbTiO₃）在室温下同样属于多铁性材料……
