  • Abstract
    Crystallographic and magnetic properties of Sm2Fe17-xSix with x=0, 0.5, 1.0, 1.5, 2.0, and 2.5 have been investigated. X-ray diffraction and thermomagnetic analyses showed that all samples studied are single-phase with Th2Zn17 structure. The Curie temperature increases with increasing Si content, although the lattice parameters decrease. Anomalous thermal expansion of Sm2Fe15Si 2 was observed below Curie temperature by high-temperature X-ray diffraction experiments
