Abstract
The spin dynamics in some two-dimensional (2D) triangular Cr-antiferromagnetic frustrated lattices, i.e. HCrO2, LiCrO 2, and NaCrO2 with ordered rock-salt structure as well as the delafossite compounds CuCrO2 and AgCrO2, has been investigated by Electron Spin Resonance (ESR). On approaching the Néel temperature TN from above, the divergence of the temperature dependent linewidth is well described in terms of a Berezinskii-Kosterlitz- Thouless (BKT) like scenario due to magnetic vortex-antivortex pairing. © 2010 IOP Publishing Ltd.
