About Quantum Magnetic Materials Team
Exploring quantum materials with novel magnetic properties
In quantum materials, their electronic properties cannot be described by the semiclassical, single-particle picture but require quantum-mechanical description. As such, quantum materials display a wide variety of exotic and functional properties including quantum magnetism, metal-insulator transition, and superconductivity, to name a few, and those properties may be exploited as components of future innovative devices.
We are exploring quantum materials realizing novel magnetic and electronic phases and functions with particular focuses on large electronic entropy, spin-orbital entanglement, and frustration.
Specialized Research Field
Functional properties of electronic entropy
Quantum materials often possess a large electronic entropy associated with multiple degrees of freedom of correlated electrons.
We aim to make use of the electronic entropy in heat storage or solid-state cooling functions. Particularly, we are searching for materials showing a large electronic entropy change coupled with structural instabilities.
Magneto-thermal transport in quantum magnets
Spin fluctuations or unconventional magnetic excitations in quantum magnets may influence their thermal properties via spin-phonon or magnon-phonon interactions.
We explore magnetic materials exhibiting giant thermal responses to magnetic fields as an approach for thermal management of materials.
Novel electronic phases in spin-orbit-entangled systems
In 4d/5d transition-metal compounds, the interplay between moderate electron correlations and strong spin-orbit coupling has been expected to give rise to a plethora of novel electronic phases including quantum spin-orbital liquid and spin-orbit-coupled superconductivity.
We have been pursuing 4d/5d compounds with such exotic phases.
