Synthesis of SmFeAsO by an easy and versatile route and its physical property characterization
We report synthesis, structure, electrical transport, and heat capacity of SmFeAsO. The title compound is synthesized by one-step encapsulation of stoichiometric FeAs, Sm, and Sm 2 O 3 in an evacuated ( 10 − 5 Torr ) quartz tube by prolong (72 h) annealing at 1100 ° C . The as-synthesized compound...
