Abstract

By using the advantages of a pulsed neutron technique, we have studied the spin dynamics of an inorganic spin-Peierls compound, CuGeO₃. The S(Q, E) changes drastically on crossing the transition temperatures. The low-lying triplet excitation which separates from the excitation continuum have been confirmed in the dimerized phase. A detailed data analysis on a two-dimensional S(Q, E) data could give a new opportunity to detect the effect of higher-order interactions on a spin-wave dispersion at various temperatures.
