New materials research leads to the discovery of new phenomena.
By learning the state of art techniques of both synthesis and low
temperature measurements, you may discover your own material,
which shows new functions, paving a path for new technology.
The discovery of new phenomena is at the forefront of research in condensed matter physics. This is particularly true for the inorganic materials, which provide an important basis in current electronic and information technology. They have been central subjects of basic research because quantum correlations among the Avogadro numbers of electrons lead to exotic macroscopic phenomena such as superconductivity, quantum Hall effect, and quantum criticality. Thus, the search for new materials that exhibit new characteristics is one of the most exciting and important projects in the materials research. We have synthesized new materials in so-called strongly correlated electron systems including transition metal compounds and heavy fermion intermetallic compounds. Our interest lies in macroscopic quantum phenomena such as novel quantum criticality, exotic superconductivity and quantum spin liquid in magnetic semiconductors.

Introduction of the study
One of our primary interests is the search for new materials that exhibit new quantum phenomena. In our group, we synthesize new materials in so-called strongly correlated electron systems including transition metal compounds and heavy fermion intermetallics. Currently we study, (1) low-temperature electronic and magnetic properties of the new transition metal compounds, (2) quantum spin-orbital liquid in two-dimensional magnetic semiconductors, (3) exotic superconductivity and quantum critical phenomena in heavy fermion systems (4) macroscopic topological effects in frustrated magnets. We also study novel Hall effects that arise owing to a complex nano-spin-structure, which allows antiferromagnets to function as a non-volatile memory without using rare-earth or precious metals.
New materials research often leads to the discovery of new phenomena. By learning the techniques of both synthesis and low temperature measurements, you may discover your own material and be filled with surprise. Through our weekly seminars, in which we review the techniques employed at the forefront of condensed matter physics, you will gain the insights to understand novel physics principles, which can then be clarified by your own experiments. I believe that this will be one of the experiences that you will come to treasure in your life.
