Self doping effect and successive magnetic transitions in superconducting Sr${}_2$VFeAsO${}_3$

Guanghan Cao, Zhifeng Ma, Cao Wang +14

We have studied a quinary Fe-based superconductor Sr${}_2$VFeAsO${}_3$ by the measurements of x-ray diffraction, x-ray absorption, Mössbauer spectrum, resistivity, magnetization and sp…
