Abstract
The effect of carbon on magnetostrictive properties and microstructure of the quarternary Tb0.3Dy0.7Fe2Cx alloys prepared by arc-melting and homogenization have been investigated. Magnetic properties, X-ray diffraction and magnetostriction studies were carried out. With increasing x, saturation magnetization decreases substantially, but the magnetostriction measured at a field of 2T(λ2T) increases slightly with x<0.1 (0.43 wt.%). By further increasing x, λ2T decreases rapidly, and a second phase, (Dy,Tb)Fe3C with Curie temperature 340°C, appears, and it becomes the dominant phase at x⩾0.2
