Near the collapse of ferromagnetism in CeFe2 under high pressures

The magnetization of single crystalline CeFe2 was measured in the temperature range from 2 to 300 K under hydrostatic pressures up to 8 kbar. The magnetization at 5 K along the each principal axis in CeFe2 was quite anisotropically suppressed even in the cubic symmetry by applying hydrostatic pressure, that was mostly pronounced along the [111] axis. Such an anisotropic suppression of magnetization might occur as a result of an anisotropic suppression of the antiferromagnetic spin fluctuations due to magnetic field coming from the anisotropic Ce 4f-Fe 3d hybridizations with strong magnetoelastic effect (C) 2001 Elsevier Science B.V.
