Graphite intercalated compounds proved to be a particulary fertile system on which to study phase transitions. In the case of FeCl3 intercalated graphite as well as the in-plane densities and defects play an extremely important role, and add to the variety of critical phenomena to be observed. The investigation so far has yielded many interesting results on well characterized samples. We have studied the magnet properties of our samples as a function of defects, probed by the Mossbauer technique, in-plane densities of the intercalant, and stage. Scientifically, the interest is in the nature of these transitions and their comparison to the various models such as the x-y model, the Potts model and various other models, such as a spin glass, which predict anomalies in two dimensional systems which in the lower stages might become three dimensional in character.
