SmFeAsO1-xFx type oxypnictide bulks were made via a single-step synthesis. Polycrystalline bulk samples with nominal composition SmFeAsO1-xFx (x=0.35 and 0.4) were synthesized by conventional solid state reaction using the starting powders SmF3 , Sm, Fe, Fe2O3 , and high-purity As (specifically allotrope-gray arsenic). The weighed powders were thoroughly ground by hand with a mortar and pestle and pressed into pellets in an argon-filled glove box. The pressed pellets were sealed in an evacuated quartz ampoule and heat treated at 1100°C using different ramp rates to reach the reaction temperature. Magnetization vs. temperature measurements were made on the various specimens, where a maximum onset Tc of 55 K was achieved.
