N2 - Electron spin resonance (ESR), at 9, 94, and 190 GHz, and magnetization studies on polycrystalline, powder, and ultrafine powder samples of (Formula presented) (NINAZ) have revealed several effects arising from the Haldane phase. Using the (Formula presented) value of the end-chain spin (Formula presented) as determined by ESR, our results confirm that the end-chain spins are (Formula presented) and show no evidence for (Formula presented) end-chains. In addition, the ESR signals reveal spectral weight consistent with a model describing interactions between the end-chain spins on the shortest chains and between the magnetic excitations on the chains and the end-chain spins.
