摘要
The Cl, Cs, and H nuclear magnetic resonance are used to examine the magnetic structure of antiferro-magnetic Cs Mn Ck32H2O. The magnetic space group is P2bc'ca'', and the structure consists of eight sub-lattices with the sublattice magnetization along the b axis. The linear chains invoked by other authors to explain the high-temperature anomaly in the susceptibility and specific heat are shown to be antiferro-magnetic. The large intrachain exchange postulated by these authors and the rather small observed Néel temperature are shown to be reconciled by the Green's-function theory of the Néel temperature, provided the exchange between the chains is assumed to be relatively small.
