Abstract
One of the most fascinating frustrated antiferromagnets, CuFe O2, contains stacked hexagonal layers, each with an magnetic structure. Recent neutron-scattering studies have found that the spin-wave spectrum softens with increasing magnetic field or by substituting Al for Fe. We present a theory of the spin-wave excitations that fits the observed frequencies quite well and explains this softening.
