Abstract

We report the first inelastic neutron scattering measurements on the rhombohedrally stacked triangular antiferromagnet NaCrO_2 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 T_c. Our results show that strong spin fluctuations persist far below T_c and that dispersive spin wave excitations only appear near the cross-over temperature 0.75T_c.
