Multiferroic materials are of great interest, since they provide the simultaneous presence

of (anti-)ferromagnetic, (anti-)ferroelectric and (anti-)ferroelastic ordered regions within

a crystal. Unfortunately, most systems that have been investigated so far exhibit these

extraordinary properties only at low temperatures. In view of possible applications in

information technology, sensor technology etc., it is therefore a crucial task to increase

the temperature range of multiferroics. Since the exact mechanism of spin coupling with

the movement of ions and the resulting electric dipole moment is still not fully
