Abstract

Magnetic excitations of the spin-Peierls compound CuGeO₃ under applied pressure of 2 GPa have been studied. The dispersion along the chain direction up to the zone boundary has been obtained. The spin-Peierls gap energy increases to 4.2 meV and the zone boundary energy decreases to 14.1 meV. The pressure dependence of dispersion relation can be interpreted by the increase of the next-nearest-neighbor intra-chain interaction under applied pressure causing the increase of both the spin-Peierls gap energy and transition temperature.
