摘要
Pressure effects on the Curie temperature and spontaneous magnetization in ferromagnetic Hf(Fe1-xCox)(2) with the cubic Laves phase structure have been investigated under high pressures up to 1.2GPa. An anomalously strong pressure dependence of the Curie temperature is observed around x = 0.725. A collapse of ferromagnetic moment under pressure is also observed at x = 0.6 and 0.65. These results are discussed on the basis of the spin fluctuation model of itinerant-electron metamagnetism. (c) 2006 Elsevier B.V. All rights reserved.
