摘要：

The interchain exchange integral J' along the b-axis of the spin-Peierls system CuGeO3 is estimated by analyzing the exchange splitting of EPR spectra observed at T = 300 K under ultra-high magnetic fields up to 100 T. The evaluated magnitude of J' (similar to 0.4 meV) is smaller than that estimated from the inelastic neutron scattering measurements. (C) 1998 Elsevier Science B.V. All rights reserved.
