Pressure-induced antiferromagnetism in fcc Fe-Ni Invar alloys
Received 30 November 1987, Available online 9 August 2002.
Abstract
We report the experimental observation of a pressure-induced magnetic phase transition in the ferromagnetic fcc Fe68.5Ni31.5 Invar alloy. It is shown that above a critical pressure of 5.8 GPa the system displays antiferromagnetic order at low temperatures. The Néel temperature decreases on further increasing the pressure. The experimental results are compared with several related theoretical models.
