FexTe thin films were prepared on SrTiO3 (001) substrates by molecular beam epitaxy in a well-ordered epitaxial layer-by-layer fashion. The composition of the films was varied by adjusting the Te flux in a Te-limited growth regime. Changes in the electronic structure were systematically studied using x-ray absorption spectroscopy at the Fe L2,3 and Te M4,5 edges and x-ray photoelectron spectroscopy of core levels and valence band. We found that FeTe with optimized composition (Fe/Te ratio ≈ 1) provides the sharpest spectral features, indicating that Fe1.00Te can be synthesized as a thin film, although it is not possible in bulk.

Layered perovskites of general formula AA'CuFeO</a:mi>5</a:mn></a:msub></a:math> are characterized by the presence of spiral magnetic phases whose ordering temperatures <b:math xmlns:b="http://www.w3.org/1998/Math/MathML"><b:msub><b:mi>T</b:mi><b:mi>spiral</b:mi></b:msub></b:math> can be tuned far beyond room temperature by introducing modest amounts of Cu/Fe chemical disorder in the crystal structure. This rare property makes these materials prominent candidates to host multiferroicity and magnetoelectric coupling at temperatures suitable for applications. Moreover, it has been proposed that the highest <c:math xmlns:c="http://www.w3.org/1998/Math/MathML"><c:msub><c:mi>T</c:mi><c:mi>spiral</c:mi></c:msub></c:math> value that can be reached in this structural family (<d:math xmlns:d="http://www.w3.org/1998/Math/MathML"><d:mo>∼</d:mo><d:mn>400</d:mn></d:math> K) corresponds to a paramagnetic-collinear-spiral triple point with potential to show exotic physics. Since generating high amounts of Cu/Fe disorder is experimentally difficult, the phase diagram region beyond the triple point has been barely explored.
