CO-59 NMR IN STACKED TRIANGULAR LATTICE ANTIFERROMAGNET CSCOBR3

From Co-59 NMR at 484.5 MHz in Ising-like antiferromagnet CsCoBr3 in t he low temperature phase, we found the antiparallel coupling Co2+ spin s along the c-axis together with the pseudo-field effect. The zero-fie ld spectra, however, including a weak component besides the main lines suggest that sublattices cant in CsCoBr3 unlike the ferrimagnetic str ucture in CsCoCl3.
