Disordered Matter
Disordered matter is ubiquitous in our daily live. Especially its electrical applications are numerous, e.g. the use of doped crystalline and amorphous semiconductors as standard materials for electronics or solar cells, glasses and polymers as insulator materials, or ionic conductors as solid electrolytes for accumulators and fuel cells. In our group, disordered matter is mainly investigated using...
Exotic Groundstates
In recent years, the study of exotic ground states, especially in transition-metal oxides and chalcogenides has become a very active area of solid-state physics. Examples include magnetically frustrated states like, e.g., spin liquids, orbital-liquid and orbital-glass phases, charge order, and heavy-fermion states. These complex ground states...
Magnetism
Due to only partially filled electronic d shells, the physics of transition-metal compounds is characterized by a complex interplay of electronic spin, orbital, and charge, aswell as of the lattice degrees of freedom.
These electronic correlations give rise to various ordering phenomena...
Superconductivity
The discovery of Fe based superconductors in 2008 showed that the unconventional (high-temperature) superconductivity in cuprates is not unique but can occur in other material classes, too. The highest TC of this class of novel superconductors to date is 56.3K and was found already found in 2008 for(Gd0.8Th0.2)FeAsO, a member of the so-called 1111-family.
Subsequently the 122-family was discovered...
