摘要：

The ferromagnetic (FM) La(Fe//0//. //8//6Al//0//. //1//4)//1//3 Invar alloy displays a pressure-induced FM to antiferromagnetic (AF) phase transition at a pressure as low as p APP 1STH 0. 1 GPa. A quantitative analysis of the results shows that the FM yields AF magnetic phase transition recently observed in La(Fe//xAl//1// minus //x)//1//3 at ambient pressure is governed by the decrease of the unit cell volume rather than the increase of the number of Fe nearest neighbor atoms.
