Single crystal growth and magnetic, transport and thermal properties under extreme condition of rare earth compounds
For recent years, intermetallic compounds including rare earth elements ( especially Cerium, Samarium, Europium and Ytterbium ) have attracted much attention because of their anomalous physical properties such as heavy fermion, valence fluctuation and dense Kondo effect. These anomalous physical properties are thought to arise from the interaction between 4f electron of rare earth ion and ligand conduction electrons. Therefore, it is expected that their physical properties are very sensitive to the application of pressure and magnetic field. We are trying to measure magnetic, transport and thermal properties under extreme conditions in order to make clear the origin of anomalous physical properties.
Development and optimization of thermoelectric materials at low temperature
Recently, thermoelectric materials have been much interest as new and clean energy conversion materials. We focus on development and optimization of new thermoelectric materials for low-temperature usage. Our purpose is to optimize thermoelectric properties at low temperature by substitution of constituent elements, impurity doping and improvement of preparation method.
