複合極限下における物性測定装置開発とそれを用いた特異な電子状態を持つ物質の電子物性の研究

抄録

  A versatile high-pressure apparatus has been constructed to measure the electronic, magnetic and thermal properties of metals, alloys and compounds at low temperature and high magnetic field. A pressure-induced crossover from heavy fermion to intermediate valence state and pressure-induced superconductivity are reported for some intermetallic compounds including f electrons. The effect of pressure on the giant magnetoresistance (GMR) for nanoscale magnetic materials is described. The enhancement of GMR is found at high pressure. The Compton scattering at high pressure is also reported as an interesting topic.
