Single-Step Synthesis of Sr4V2O6Fe2As2: The Blocking Layer Based Potential Future Superconductor
We report synthesis, structural details and transport measurements on Sr 4 V 2 O 6 Fe 2 As 2 . Namely, the stoichiometric amounts of V 2 O 5 +1/2×SrO 2 +7/2×Sr+2×FeAs are weighed mixed, ground thoroughly and palletized in rectangular form in a glove box in high purity Ar atmosphere. The pellet is fu...
