IronI 7100 Crystal Structure, Thermal Expansion and Magnetic Properties of New Com-

pound Dy1.2Fe4Si9.8. — The new title compound is prepared by arc melting of the ele-ments followed by annealing at 900 °C (evacuated quartz tube, 30 d, quenching). Dy1.2Fe4Si9.8 crystallizes in the hexagonal space group P63/mmc (Er1.2Fe4Si9.8-type structure; powder XRD). The unit cell parameters increase with increasing temperature in the range from 298 to 1013 K. The effective paramagnetic moment of the compound is 11.3 μB per formula unit. — (HE*, W.; ZENG, L.; HUANG, J.; ZHANG, J.; J. Alloys Compd. 458 (2008) 1-2, 83-87; Key Lab. Nonferrous Met. Mater.
