Condensed matter physics in 100 – 1000 T ultrahigh magnetic fields
Yasuhiro H Matsuda
University of Tokyo, Japan
Ultrahigh magnetic field in the range of 100-1000 T opens new research fields in condensed matter physics. The spin
Zeeman energy of a free electron reaches 1350 K (0.116 eV) at 1000 T that is large enough to change electronic as well
as structural properties of matter. Various kinds of phase transitions can be induced by such ultrahigh magnetic fields and
the novel high-field phase is regarded as a kind of new material. Destructive ways are only available for generation of the
100-1000 T fields and thus the time duration of the pulsed-fields is in the microsecond range, which requires us to develop
special measurement techniques to overcome this severe condition. For magnetic field generation, the single-turn coli and the
electromagnetic flux compression techniques have long been developed in our institute (the Institute for Solid State Physics
(ISSP)) and can generate up to 300 and 1000 T, respectively. Various kinds on intriguing phenomena such as the structural
phase transition of solid oxygen, magnetic phase transitions in low dimensional magnets, novel spin-state transitions in cobalt-
oxides, and the insulator-metal transition in a Kondo material are recently discovered in ultrahigh magnetic fields. Such recent
physical achievements as well as developments of magnet technology are presented.
