概要
- 論文の詳細を見る
The thermal expansion of MnTe2 has been measured. A small anomaly in thermal expansion has been observed at 00K, which is probably due to a change of internal parameter of crystal. The coefficient of thermal expansion has been separated into lattice, magnetic and Schottky contributions. The magnetic entropy associated with an antiferromagnetic ordering is computed from the observed coefficient of thermal expansion to be (l0.8 0.18)J/K*mol. It is con-cluded that in MnTe2 zero field splitting of the 6S512 is small. The Grtineisen constant for Schottky contribution is negative.
