Recent progress in high field magnetism
Japan Atomic Energy Research Institute, Japan
This paper describes recent progress in high field magnetism mainly done in the Research Centre for Extreme Materials, Osaka University, with a short survey of the history. The main activities are concentrated on the condensed matter physics covering the field of magnetism and superconductivity where a common keyword is ’highly correlated electron physics’. A wide range of studies of metamagnetism, field-induced electronic transitions under high field, is summarised. These high field states are regarded as field-induced quantum states with various novel properties. High field is also effective for various atomic and molecular sciences. Nonlinear Zeeman effect, field-induced transparency and diamagnetic orientation of organic and biological materials are shown as examples. New frontiers in the high field technologies are shown with a highly sensitive magnetometer using the dynamical Faraday effect.
