Sensing Behavior of Varied Stoichiometry Single Crystal Fe-Ga

Abstract

Iron-Gallium (Fe-Ga) alloys are promising materials for sensing applications. However, the mechanical and magnetic properties of these materials vary significantly with the percentage of gallium, which motivates this study on the effect of stoichiometry on the behavior of Fe-Ga alloys. Major loop compressive tests (loading to 110MPa and unloading, at magnetic fields ranging from 0 to 891 Oe) were performed on single crystal 19 and 24% Ga samples with longitudinal axis in the [100] direction. The effect of% Ga on the magnetomechanical properties is discussed. Furthermore, the magnetic interaction between the Fe-Ga sample and the remainder of the magnetic circuit is modeled.
