THE INORGANIC SPIN-PEIERLS COMPOUND CUGEO3

A review of recent experimental results obtained on the inorganic spin -Peierls compound CuGeO3 is proposed. As the spin-Peierls phenomenon r esults from the interplay between lattice and magnetic (quantum) fluct uations, the presentation focuses on the different dynamical aspects o f the problem. With CuGeO3, many points have been clarified and new re sults acquired. However, it remains open questions which, due to the h igh quality of the available crystals, can be expected to be solved in the future.
