Magnetic Structure of Superconducting FeTeOx Films by Neutron Scattering

ORAL

Abstract

We present the temperature-dependent neutron diffraction studies of superconducting FeTeO$_x$ and non-superconducting FeTe films grown by PLD.\footnote{\textbf{Appl. Phys. Lett.} 103, 102604 (2013)} In both cases we were able to get strong elastic, magnetic neutron peaks even though we were using film samples. Both samples had magnetic scattering similar to that of bulk Fe$_{1.05}$Te, indicating the coexistence of magnetism and superconductivity in the oxidized films. We will present a detailed analysis of the differences in magnetism between the superconducting and non-superconducting samples.
