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