Abstract
High quality FeSe0.5Te0.5 (FST) epitaxial thin films were successfully prepared on SrTiO3 (STO), MgO and LaAlO3 substrates with a TiO2 buffer layer by pulsed laser deposition method, respectively. We present the results of a collaborative study on the superconducting and magnetic properties of the three types films, such as the critical temperature T c, the anisotropy, and the critical current density J c. A stronger matching between film and substrate plays an important role in enhancing the superconducting and magnetic properties. FST film on STO substrate shows the high superconducting transition temperature T c about 14.6 K and the largest critical current density J c above 106 A cm−2 at 4 K in self-field. In addition, the high-angle annular dark field imaging implies the interface sharpness at FST/TiO2 heterostructure, contributing to a deep understanding of bonding for the iron-based superconductors.
