Abstract
The correct stacking of hexagonal layers is used to obtain accurate estimates for the exchange and
anisotropy parameters of the geometrically-frustrated antiferromagnet CuFeO2. Those parameters
are highly constrained by the stability of a collinear metamagnetic phase between fields of 13.5 and
20 T. Constrained fits of the spin-wave frequencies of the collinear ""## phase below 7 T are used to
determine the magnetic unit cell of the metamagnetic """## phase, which contains two hexagonal
layers and 10 Fe3+ ions.
