Abstract
Raman measurements were performed on K2CoF4, a two-dimensional antiferromagnet with large uniaxial anisotropy. Two lines at 206.5 and 468 cm-1 were identified as the AFMR and two-magnon lines respectively. Measurement of the temperature dependence revealed an extremely weak renormalisation of these excitations up to TN=107.4K.Keywords
