Abstract
The magnetostatic properties of K2Co x Fe1−x F4 have been investigated by susceptibility and Mössbauer measurements at different concentrations and temperatures. Three magnetically ordered phases are found: a planar phase, an OAF phase, and an uniaxial phase. The experimental results are compared to a molecular-field calculation. At certain concentrations and temperatures it is not possible to obtain a good least squares fit of the Mössbauer spectra, which is tentatively assigned to relaxation effects due to fast spin fluctuations at the OAF phase transition.
