Magnetic structures and electronic properties of low-dimensional and frustrated intermetallic f systems

This project is focused on experimental studies of the magnetic structures and electronic properties of intermetallic systems based on f-elements, in which the magnetic f ions form low dimensional structures and/or potentially frustrated networks. In such systems, a combination of geometrical frustration, magnetic low-dimensionality, and single-ion (Rare-earth elements) or two-ion (U) physics might result in the stabilization of highly unusual ground states. Many of such systems are new or remain poorly explored. We plan to grow high-quality single crystals of these systems and to investigate the magnetic structures and other electronic properties, which will be measured under extreme conditions. Particularly detailed studies of the magnetic structures will be performed by neutron diffraction. This work is expected to clarify the role and interplay of different interactions and underlying mechanisms of geometrical frustration and low-dimensional electronic properties. This topic might have technological impact in future applications of multiferroic materials, relaxors, and glasses.
