โœฆ Synopsis

The crossover behavior from collective to local spin motions in diluted antiferromagnets is discussed using the canonical molecular dynamics method without introducing any ad hoc approximations to the equations of motion. The calculated dynamic responses are compared with the recent results obtained by neutron inelastic scattering experiments.

In this paper we review the experimental situation concerning magnetic fluctuations and excitations in quasi-Heisenberg antiferromagnetic (AF) chains, as observed in prototypes of the classical (TMMC), S = l/2 (CPC) and S = 1 (NENP, CsNiCI,) systems, by inelastic and quasielastic neutron scattering.
