The Institute "Quantum Phenomena in Novel Materials" is investigating fundamental aspects of collective quantum phenomena in condensed matter such as magnetism and superconductivity.  We are aiming at understanding the macroscopic properties of such materials from their microscopic structure and dynamics. For this purpose, the samples under study are frequently exposed to extreme conditions such as temperatures close to absolute zero, high magnetic fields, and high pressure. The spectrum of investigated systems ranges from model materials that are approximate realizations of idealized theoretical concepts to technologically interesting systems such as magnetic nanomaterials.

In the area of quantum magnetism and frustrated magnets current work includes neutron scattering experiments on various systems like the quantum spin liquid candidate Ca10Cr7O28, the quantum spin ice candidate Nd2Zr2O7, and the one-dimensional Heisenberg–Ising antiferromagnet SrCo2V2O8. In the area of strongly correlated electron systems, we participate in the ongoing quest for a comprehensive and final understanding of the consequences of strong correlations and related emerging phenomena. In this process, we made significant contributions, e.g. to the discovery and characterization of charge ordering phenomena in cuprate high-Tc superconductors. In the area of novel oxides, we focus on transition metal oxides which are of great potential for technological applications since they show a wide range of extraordinary properties like multiferroic behavior, colossal magnetoresistance, and high-Tc superconductivity. Finally, in the area of magnetic nanomaterials, our research activities focus on systems related to potential applications in spintronics and magnetoelectrics.
