Abstract

We report the first inelastic neutron scattering measurements on the rhombohedrally stacked triangular antiferromagnet NaCrO2 which has recently been shown via μSR and NMR measurements to exhibit an unusually broad fluctuating cross-over regime extending far below the onset of spin freezing at Tc. Our results show that strong spin fluctuations persist far below Tc and that dispersive spin wave excitations only appear near the cross-over temperature 0.75 Tc.
