Structural, dielectric and Raman spectroscopic study of complex electric and magnetic interactions in multiferroic ionic crystals

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 understood, detailed experimental and theoretical studies are needed which require advanced techniques like high-resolution Raman spectroscopy with suitable laser sources.
