摘要：

La(FexSi1-x)(13) compounds exhibit an itinerant-electron metamagnetic (IEM) transition above Curie temperature T-C. The IEM transition in the compound with x=0.88 is accompanied by a giant volume change. From a practical viewpoint, T-C was controlled by hydrogen absorption in order to obtain such a giant volume magnetostriction at room temperature. For the La(Fe0.88Si0.12)(13)H-1.0 compound, the IEM transition occurs above T-C=278 K, and a significant isotropic linear magnetostriction of about 0.3% at 7 T is induced in the vicinity of room temperature. This large magnetostriction is attributed to the giant volume magnetostriction of about 1% by the IEM transition. (C) 2001 American Institute of Physics.
