概要
- 論文の詳細を見る
Itinerant-electron magnetic properties of Lu (Co_<0.90>Al_<0.10>)_2 Laves phase intermetallic compound under high pressures up to 1.0 GPa have been investigated. The compound has a critical concentration of the onset of ferromagnetism. The spontaneous magnetization decreases with increasing pressure and disappears above 0.6 GPa. In the paramagnetic state induced by applying pressure, a metamagnetic transition from a paramagnetic to ferromagnetic state occurs in magnetic fields. An anomalously large negative pressure dependence of the Curie temperature has observed, which is explained by the Landau expansion of free energy taking spin fluctuations into consideration.
