摘要: Inelastic neutron measurements have been performed on a quasi-one-dimensional spin-gap system CuNb 2 O 6 . From the dispersion curve of triplet excitation, compound has found to ferromagnetic-antiferromagnetic alternating bond chain. The temperature ( T ) dependence magnetic excitation spectra indicates that both singlet correlation and antiferromagnetic begin grow with decreasing at around 0 , where spin susceptibility becomes maximum.
