dc.description.abstractWe report 57~e Mõssbauer measurements in the diluted Ising antiferromagnet Fe0.25Zn0,75F2 at temperatures between 4.2 and 28 K. DC susceptibility measurements in the same sample show a spin-glass phase at a freezing temperature Tg = 10K. We found that for this concentration there is a competitive coexistence of spin-glass behaviour and antiferromagnetic order. The freezing temperature is frequency-dependent and follows a power law
