Strongly Correlated Electrons and Neutron Scattering
Hidetoshi Fukuyama
Abstract
Various aspects of close and interesting relationship between antiferromagnetism and singlet ground states are introduced for which neutron scattering have been playing vital roles. The special emphasis is on the disorder-induced antiferromagnetism in spin-Peierls systems, which can be viewed as a nucleation process of classical magnetic order in the background of singlet state whose origin is purely quantum-mechanical. It is then pointed out that similar features will be found in CexCu2Si2 and high Tc cuprates. Finally the possible charge ordering process in NaV2O5 is discussed which leads to the quenching of localized spins.
