✦ Synopsis

Dynamical magnetic properties of the quasi-one-dimensional spin-gap system CuNb 2 O 6 have been studied by means of neutron inelastic scattering. The dispersion curve of the singlet-triplet excitation indicates that the system has ferromagneticantiferromagnetic (F-AF) alternating bond chains, which is the origin of the spin gap. The magnetic excitation and the macroscopic properties are analyzed by the F-AF alternating bond model. The impurity effect of this system is also studied.
