MgF2 Doping of SmFeAsO Superconductors Prepared by Mechanical Alloying and Rapid Annealing

Magnesium and fluorine codoped Sm1–x/2Mg x/2FeAsO1–x F x (x = 0 – 0.3) superconductors were prepared by the process of mechanical alloying and subsequent rapid sintering. The transition temperature (T c) increases with x and reaches 53.3 K at x = 0.3, accompanied by decreased lattice parameters. Ele...
