Abstract
We experimentally show that in the inorganic spin-Peierls compound CuGeO3 the inelastic-neutron-scattering intensity with ΔE=1 meV at (0,1,0.5) exponentially decreases below TSP(=14 K) due to the formation of the spin-Peierls gap. We also found that the magnetic excitation spectrum exhibits a pronounced energy dispersion, the intrachain and interchain exchange parameters Jc10.4 meV, Jb0.1Jc, and Ja-0.01Jc, and the gap energy at T=0 K is 2.1 meV, suggesting that Jb/Jc0.1 is rather large compared to the organic spin-Peierls system.
