| Abstract: | The deviation from the 1D antiferromagnetic behaviour in Ag0.50Cr0.50PS3 is greatly enhanced by substitutional or electron - irradiation - induced disorder. Accordingly, we interpret this deviation as a contribution of unpaired spins related to finite length of antiferromagnetic segments and to isolated magnetic defects. In the case of short segments, a strongly field dependent susceptibility is observed in the temperature range of 1D interactions, suggesting a possibility of 1D spin glass behaviour. |
