We still have many opportunities for making a great discovery
for the human beings. Challenges to unexplored extreme
conditions are the key to make the breakthrough.
"Gijyutsu" in Japanese can be translated to "engineering", or "technique", or sometimes "art". That is a word given by my class teacher to me when I was a high school student. I thought that he suggested me to utilize the scientific techniques for my future job.
I have been working on the research of high magnetic fields for twenty-two years since I started the bachelor thesis study. Generation of high magnetic fields may sound simple and rather easy. However, it actually requires advanced techniques and therefore there are lots of unsolved physical problems that require the high magnetic fields. It is very exciting to conduct the experiments at extremely high magnetic fields that are only available in our laboratory. We have many chances to solve such interesting and important issues. A material that we think we understand very well may behave very differently in high magnetic fields owing to its excited state that is usually hidden in a normal condition. There are opportunities to discover new and important phenomena at the very high magnetic fields.
In condensed matter physics, we treat 1023 atoms and only know a part of the phenomena given by them. In experimental research of material science, a researcher basically proceeds with his or her work independently. It is quite exciting and a really good experience to find something new by his or her own experiment. In the microscopic world of matter we still have lots of possibilities of great discoveries. Why don’t you join this exciting and challenging research?

Introduction of the study
We have studied various kinds of interesting phenomena induced by applying strong magnetic fields. A 700 Tesla-magnetic field that is a world record for the laboratory experiment is utilized by means of destructive magnets. Aim of our research is to find new phenomena that are intrinsically different from that at weak magnetic fields and to understand them. In such strong fields, the Zeeman energy exceeds an energy scale of room temperature and the effect of shrinkage of wave function causes a breakdown of the effective mass theory. Therefore exotic phenomena possibly take place in the high magnetic fields. Our current research subjects are: (1) Magnetization process of quantum spin systems, (2) Quest of magnetic-field-induced phase transition of solid oxygen, (3) Insulator-metal transition at strong magnetic fields,
(4) Electronic state of heavy fermion compounds in high magnetic fields, (5) Cyclotron resonance in ferromagnetic semiconductors, and others. Development of experimental techniques is very important for the research of strong magnetic fields. Creative ingenuity and skilful techniques are the key to success of experiments and get precious results that cannot be obtained in other place in the world.
Message from a senior
Matsuda-sensei is a nice gentle person. He basically instructs students so that they enjoy their research by their own ideas. When I face with a difficulty of experiments I visit him to discuss the problem. At such time, Matsuda-sensei readily comes up with an idea to realistically solve it. He is so friendly and sometimes gives me an advice for the life.
There are three ultra-high magnetic field facilities in the world. (Japan, USA, Europe) Japan leads the science at the very high magnetic fields. The data we get from the high-magnetic-field experiments are very precious and only obtainable in our laboratory. I think it is very exciting to explore a new research field using high technology of Japan. I envisage that such research achievements might result in some awards like Novel prize.
In Kashiwa campus, state-of-the-art research environments are well equipped in the open space. Please join us and try the great research.
