Abstract
Electron paramagnetic resonance has been observed on in ultrahigh magnetic fields up to 180 T. The distinct exchange splitting is found between the two inequivalent sites along the axis. Analyzing the data on the basis of a simple two-spin model, we evaluated the interchain exchange coupling as ∼0.9 meV. This value is a little smaller than obtained by neutron-scattering experiments.
