T. Kohmoto et al., SUBLATTICE SWITCHING IN THE 3-DIMENSIONAL ORDERED PHASE OF THE TRIANGULAR-LATTICE ANTIFERROMAGNET CSCOCL3, Physical review. B, Condensed matter, 52(17), 1995, pp. 12526-12529
A double-resonance experiment of Cs-133 NMR was performed in the three
-dimensionally ordered phase of a triangular-lattice Ising-like antife
rromagnet CsCoCl3. The spin inversion in the Co2+ chain was detected b
y observing the change of the internal magnetic held at the Cs site. T
he inversion times, which are of the order of 10(2) s at liquid helium
temperatures, were obtained from an analysis by the rate equations. T
his spin inversion is a slow dynamics and is interpreted as a result o
f the sublattice switching arisen from the movement of the ferrimagnet
ic domain wall in the c plane.
