Gadolinium trisilicide − a paramagnetic representative of the YbSi3 type series
Zeitschrift für Naturforschung. B, A journal of chemical sciences
Binary gadolinium trisilicide GdSi3 was prepared by high-pressure high-temperature synthesis at typically 9.5(5) GPa and 870 K before quenching to ambient conditions. At ambient pressure, GdSi3 exhibits an exothermic decomposition at 647(10) K into the thermodynamically stable phases GdSi2–x and Si, indicating its metastable character. Powder X-ray diffraction data is consistent with the YbSi3-type crystal structure comprising slabs of condensed Si2 dumbbells, which enclose layered arrangementsdoi:10.1515/znb-2022-0024 fatcat:gqgjq762ynch3cmszzfnw55vry
