Emerging Novel Phases in Strongly Frustrated Quantum Magnets (ENIQMA), PRG4
Project Duration: 01.01.18 – 31.12.22
Principal Investigator: Dr. Raivo Stern
Frustrated spin systems exhibit a variety of behaviors ranging from exotic ground states and novel types of magnetic excitations, to the enhanced magnetocaloric effect and multiferroicity, relevant for applications. A corollary of the vibrant research in this field are new frustrated materials, both bulk and films, that hold promise for novel phases, interesting physics, and potentially useful properties. We propose to perform comprehensive studies of these materials, from both experiment and theory, aiming to provide a realistic picture of their physics on both phenomenological and microscopic level. This combined approach gives us a rare opportunity to obtain novel experimental results, understand them within a suitable theoretical framework, and use this insight for the design of new materials. Our methods include low-temperature thermodynamic and microscopic(AFM-MFM)measurements, NMR and THz spectroscopy, neutron scattering, and DFT calculations combined with microscopic modeling.

2. Unconventional superconductivity in the MonGa(5n+1) intermetallics, MOBJD449
Project duration: 01.09.18 – 31.08.20
Principal Investigator: Dr. Valeriy Verchenko
We will study unconventional superconducting states that emerge in the MonGa5n+1 intermetallic compounds at low temperatures. Unconventional superconductivity in these compounds originates from multiple superconducting gaps, as recently observed in the n = 8 representative of this family, Mo8Ga41, below TC ~ 10 K. Having in hand a clear and straight structural relationship between the n = 4, 6, and 8 representatives, we expect nontrivial superconductivity in the whole family of compounds. To shed light on microscopic properties of their superconducting states, the MonGa5n+1 compounds will be studied systematically by means of thermodynamic, transport and local probe measurements, which should pave the way for rational design of multigap superconductors.
