AboutAbout the lab
New states of matter in uncharted ultrahigh magnetic fields
The Matsuda Lab studies matter in ultrahigh magnetic fields exceeding 100 tesla.
At the Institute for Solid State Physics, two methods, the single-turn coil method and the electromagnetic flux compression method, can generate magnetic fields of 100 to 700 tesla.
The field lasts only about a microsecond, but this research makes it possible to search for unknown phenomena that appear only in ultrahigh magnetic fields, something that cannot be done elsewhere.
The lab also carries out experiments that combine ultrahigh magnetic fields with quantum beams such as synchrotron X-rays, starting with the development of the instruments.
Key terms
- Tesla
- A unit of magnetic field strength. Even the surface of a strong neodymium magnet does not reach 1 tesla.
- Quantum beams
- Intense beams of light or particles, such as synchrotron radiation, free-electron lasers, and neutron beams, that can reveal the behavior of electrons and atoms inside matter.
- Synchrotron radiation
- Extremely bright light and X-rays emitted when magnets bend the path of electrons traveling at nearly the speed of light.
- Insulator
- A material that hardly conducts electricity. It can sometimes turn into a metal under a magnetic field or other conditions.

ResearchResearch themes
The lab searches for phenomena that appear only in ultrahigh magnetic fields exceeding 100 tesla and aims to understand them. It focuses on phenomena that have been predicted by theory but not yet confirmed, and on materials that barely respond to ordinary magnetic fields.
*Illustrative imageMaterials Science in Ultrahigh Magnetic Fields Exceeding 100 Tesla
Because of the strength limits of magnet materials, fields far beyond 100 tesla can only be produced by methods that destroy the coil. Using the single-turn coil method and the electromagnetic flux compression method, the lab generates fields of 100 to 700 tesla and searches for unknown phenomena that appear only in ultrahigh magnetic fields.
*Illustrative imageSeeing the World of Strong Magnetic Fields with Quantum Beams
The lab carries out high-field experiments using synchrotron X-rays from SPring-8 and the Photon Factory, starting with the development of the techniques. Pulsed high magnetic fields, which last only a short time, pair well with intense quantum beams.
*Illustrative imageChanging Crystals and Electrons with Magnetic Fields
The lab searches for phenomena in which ultrahigh magnetic fields drastically change not only the state of electrons but also the crystal structure. For example, VO2 changes from an insulator to a metal at a field of about 200 to 300 tesla. The materials studied range from superconductors and dielectrics to proteins.
