Biography
Magnetic phenomena in condensed matter can be observed at a wide range of temperatures. In heavy fermions and certain other systems, interesting magnetic behavior often occurs at low temperatures much below 1 K. Because of difficulty in making magnetic measurements at such low temperatures, little work has been done to date. Our interest is to research those magnetic materials having low characteristic temperatures, such as f-electron compounds, heavy fermions, quantum spin systems, and geometrically frustrated spin systems. To study these systems, we also develop necessary equipment. Equipment we have successfully developed includes: high sensitivity magnetometers which are operable even at extremely low temperatures down to the lowest of 30 mK, and equipment to perform angle-resolved specific heat measurements in a rotating magnetic field. The latter is an effective tool for investigating the nodal structures of anisotropic superconductors.
