摘要：

In the specific heat measurements of Fe1-xMnxCl2-2H(2)O with competing exchange interactions and anisotropies, two peaks are observed in Fe-rich region and one sharp peak is observed in Mn-rich region. In the ac susceptibility measurements at a lower temperature than Neel point T-N no anomalies are observed in Fe-rich region and a broad maximum is observed in Mn-rich region. These results imply the existence of "intermediate" phase at the low temperature region.
