Re-entrant Spin Glass Behavior in Mn-rich YMnO3

We use magnetism and specific heat measurements to investigate the hexagonal Mn-rich YMnO{sub 3}. It is found that upon cooling from a high temperature, the compound first orders antiferromagnetically at T{sub N} {approx} 72 K and then undergoes a re-entrant spin glass (RSG) transition at T{sub SG} {approx} 42 K. This RSG behavior results from the competition between the ferromagnetic interaction and the antiferromagnetic interaction, which is related to the intrinsic geometric magnetic frustration in this system.
