Description

The crystal structures of Tb0.27Dy0.73Fe2-xSix were refined by the Rietveld analysis of their X-ray powder diffraction patterns. With the increase of Si, the lattice constant decreases. The Si only replace Fe at 16c position. When x<0.2, the alloys consist of only one phase. The concentration dependence of magnetostriction and Curie temperature of Tb0.27Dy0.73Fe2-xSix samples has been investigated. (orig.)
