Abstract:

Rapid-solidification method was applied to make Fe-15atGa and Fe-17atGa ribbons of 100 micrometers thickness. These ribbons have large magnetostriction of 270 ppm, where the coercive force exhibits a maximum value. The phenomenon is related to special metallic texture, that is, the ribbon has strongly 001-oriented textured fine columnar microstructure with grain size of 2-5 micrometers. The ribbon has little-hysteresis loop of magnetostriction and a good ductility i.e., full bending is possible. Rapid-solidified Fe-Ga alloy has a promising possibility as a new magnetic-induced sensoractuator material.
