| An influence of Si on the structural and magnetic properties of Dy(Fe,V,Si)12 compounds is studied. X-ray diffraction shows that these materials crystallise in the tetragonal ThMn12-type structure. An increase in the saturation magnetization, the Curie temperatures and magnetocrystalline anisotropy in the Si substitutional systems is observed when compared with DyFe12-xVx. The magnetic properties depend on the preferential site occupation and concentration of Si and V atoms in these compounds. |
