Ikeda Lab
Machine-translated · View original
A lab that builds its own ultra-high magnetic field experimental equipment to explore how matter changes.
AboutAbout the lab
New science brought by extremely strong magnetic fields.
The Ikeda Lab studies how matter changes in extremely strong magnetic fields, aiming to clarify the role that magnetic fields play in the world.
To generate strong magnetic fields, the lab builds its own pulsed magnetic field equipment, which creates a field by sending a large current through a coil in an instant.
Using this equipment, the lab investigates phase transitions and changes in crystal structure in solid oxygen and strongly correlated electron systems.
The lab's website says that even students can aim to achieve a new world-best result.
Key terms
- Pulsed magnetic field
- A magnetic field produced by sending a large current through a coil in an instant. It can generate strong fields while avoiding heating of the coil.
- Strongly correlated electron systems
- A group of materials in which repulsion between electrons is strong and which show diverse phase transitions. Many magnetic materials and high-temperature superconductors belong to this group.
- Phase transition
- A change of a material into a different state, such as from a metal to an insulator.

ResearchResearch themes
The ultimate dream of the Ikeda Lab is to clarify the role of magnetic fields in the world. The lab develops new methods for high-magnetic-field experiments and explores the giant magnetic-field responses of matter.
*Illustrative imageCrystal structure of solid oxygen
The lab aims to determine the completely new crystal structure of solid oxygen that has become a ferromagnet. It is already known that solid oxygen becomes ferromagnetic in a high magnetic field of 100 tesla, and the lab seeks to make use of its own 100-tesla X-ray diffraction method.
*Illustrative imagePhase transitions of matter in high magnetic fields
The lab works to discover and clarify phase transitions induced by high magnetic fields in strongly correlated electron systems. By applying an ultra-high magnetic field on the order of 1,000 tesla to LaCoO3, it has discovered multiple phase transitions.
*Illustrative imageAnisotropic electronic states of bismuth
The lab is trying to visualize in three dimensions the metallic state of bismuth, whose electronic and magnetic properties are highly anisotropic. It uses a vector pulse magnet that it developed itself.
*Illustrative imageBreaking chemical bonds with ultra-high magnetic fields
It is predicted that a magnetic field of about 100,000 tesla would break covalent bonds themselves. The lab also expects that even in the 1,000-tesla range, chemical bonds with small energies will begin to break, and it is searching for this phenomenon.
