N1 - Funding Information:
Heat capacity measurements were made with a calorimeter at the Center of Advanced Instrumental Analysis, Kyushu University, with the facilities provided by Dr. M. Watanabe. This work was supported by aid from the Nissan Science Foundation, and a Grant-in-Aid for Encouragement of Young Scientists from the Ministry of Education, Science and Culture.

N2 - Heat capacity measurements were carried out on single-crystalline CuO in the temperature range 130-300 K. Sharp peaks corresponding to the antiferromagnetic transitions were clearly observed at 211 and 227 K. At the low-temperature end, near 160 K, a wide peak in the heat capacity signal was also demonstrated. An electric anomaly was observed in the temperature range 150-160 K, which strongly suggests the possibility of a new low-temperature phase transition in CuO. This study also indicates that DSC measurement is an effective tool to detect magnetic transitions and probe subtle phase transitions in solids.
