Abstract
A random antiferromagnetic sample of the mixed crystal system Rb2MnxCr1-xCl4 (x = 0.70) with competing anisotropies and exchange interactions has been studied by quasi-elastic neutron scattering in the temperature range of 4.2-57 K. A linear temperature dependence of the observed scattering intensities as well as considerably broadened peak shapes have been found, indicating finite correlation lengths and a dynamic disorder of the antiferromagnetic phase. Below T = 11 K the onset of an additional freezing behaviour has been foundKeywords
