Superconducing SrFe$_{1.75}$Co$_{.25}$As$_{2}$ thin films grown by pulsed laser deposition

ORAL

Abstract

We are growing SrFe$_{1.75}$Co$_{.25}$As$_{2}$ thin films by pulsed laser deposition. The target was prepared by grinding and sintering a superconducting single crystal of SrFe$_{1.75}$Co$_{.25}$As$_{2}$. Typical deposition conditions are 700C and base pressure of 7x10$^{-8}$ torr. The films are grown on substrates LSAT (100) and STO (100), and their T$_{c}$(onset) range is 21-15K. We will report on structural analysis and transport measurements on the films.
