| Abstract |
We report a novel method to make FeSe/SrTiO3-x nanocomposites to observe the interfacial interaction between FeSe and SrTiO3-x grain boundaries. The oxygen-deficient SrTiO3-x nanoparticles (NPs) were successfully prepared by the annealing the SrTiO3 NPs in the presence of Mg powders in an evacuated quartz tube. The FeSe/SrTiO3-x nanocomposites were then synthesized by the solvothermal method, in which the SrTiO3-x NPs were evenly deposited on the surfaces of the FeSe NPs. Interestingly, the initial cubic morphology of the SrTiO3-x NPs is retained in the resulting nanocomposites. The nanocomposites were fully characterized by transmission electron microscopy, scanning electron microscopy, X-ray powder diffraction, and magnetization measurements using a SQUID magnetometer. Magnetic measurements of the FeSe/SrTiO3-x nanocomposites revealed typical paramagnetic behaviors and no indication of superconducting signals presumably induced by the interfacial interaction between FeSe and SrTiO3-x. |
