ARPES study of the new iron-based superconductor Sr$_{4}$V$_{2}$O$_{6}$Fe$_{2}$As$_{2}$
ORAL
Abstract
A new FeAs-based compound Sr$_{4}$V$_{2}$O$_{6}$Fe$_{2}$As$_{2}$ was discovered recently to show superconductivity at a relatively high temperature (Tc $\sim $ 37K). We will present ARPES results of band structure and Fermi surface of Sr$_{4}$V$_{2}$O$_{6}$Fe$_{2}$As$_{2}$, and discuss implications to its superconductivity.
