Web6 Jan 2014 · With the first-principles calculations, we find that the substrate-induced tensile strain tends to stabilize the collinear antiferromagnetic (CAF) state in FeSe thin film by enhancing of the next-nearest-neighbor superexchange antiferromagnetic interaction bridged through Se atoms. Web20 Jan 2024 · Iron selenide (FeSe) is structurally the simplest iron-based superconductor with the superconducting-transition temperature ( Tc) of ~9 K [ 1 ]. Intriguingly, one-monolayer (1 ML) film of FeSe grown on SrTiO 3 substrate exhibits exceptionally high Tc [ 2 ].

Web1 Dec 2024 · As indicated in Table 2, the average crystallite size changed as the weight percent ratios of FeSe 2 increased. The moderate strain also increases as the size of the crystallites decreases. This suggests that the nucleation of the particles is hindered as the amount of FeSe 2 is increased, thus resulting in less grain growth. WebElectron diffraction experiments indicate an anisotropic epitaxial strain in FeSe. A negligible strain close to 0.0% and a tensile strain of + 2.1% are observed along the in-plane [0 1 -1 … Web1 Oct 2024 · Upon increasing the compressive strain, the structure of the FeSe 4 tetrahedron is distorted along the c-axis and deviates greatly from the ideal tetrahedron structure … arpalomba
