高温超伝導体や金属磁性体等の強相関電子系が繰り出す多彩な現象を理解するという固体物性論の核心課題について,磁気励起や格子の運動を微視的に観測する中性子非弾性散乱実験がどのような情報を提供し,貢献して来たかを概観する。

A simple survey of experimental studies ever carried out by means of inelastic neutron scattering is presented mainly on systems with strongly correlated electrons. We can see how much the technique has contributed to the understanding, in a microscopic way, of origins of various physical properties, such as unusual magnetic behavior of itinerant electron systems, high-Tc superconductivity and so on, which are considered to be central issues of the modern solid state science.

Key words: inelastic neutron scattering; strongly correlated electrons; superconductors; itinerant electron magnetism; charge density waves; phonons; magmons; spin fluctuations
