“…Typically, β‐FeSe was prepared from iron and selenium at temperatures over 700 °C using conventional solid‐state reaction technique . The high‐temperature reaction is very sensitive to oxygen and purity of starting materials, which often results in the formation of a non‐stoichiometric tetragonal PbO‐type β‐FeSe phase along with a hexagonal NiAs‐type β‐FeSe phase.…”

Hybridization of nanomaterials, combined by interfacial fusion, have drawn tremendous interests because of their novel properties induced by structurally matched interfaces. Here we report a solvothermal route that can synthesize β-FeSe/SrTiO 3-x composites made of β-FeSe nanosheets (NSs) and SrTiO 3-x nanoparticles (NPs). Various spectroscopic data such as XRD, SEM, and TEM with elemental maps confirm the formation of nanocomposite architecture. Electron microscopy images of β-FeSe/SrTiO 3-x show that small SrTiO 3-x NPs in the cuboidal form are firmly bound to a sizable β-FeSe sheet with a thickness of several nanometers. The β-FeSe/SrTiO 3-x composite shows paramagnetic, which was determined using a SQUID magnetometer. The ferromagnetic property of individual FeSe NPs appears to be suppressed by interfacial interaction between β-FeSe and SrTiO 3-x , clearly showing the presence of the proximity-induced effect in the nanocomposites.

Herein, for the first time, the correlation between the phase structure and the magnetic properties of the Fe–Se system has been presented for Fe x Se y compoundswhere x/y ranges from 1:2 to 1:1. These phasesorthorhombic (FeSe2), monoclinic (Fe3Se4), hexagonal (Fe7Se8), and tetragonal (β-FeSe)were synthesized using a one-pot thermal decomposition route at the nanoscale. The magnetic properties vary enormously with change in the Fe/Se ratio due to the change in the Fe2+/Fe3+ ratio, crystal field environment around the Fe ions, magnetocrystalline anisotropy, Fe vacancies, and so forth. Among the four Fe–Se phases studied, two of them, Fe3Se4 and Fe7Se8, are ferrimagnetic below ∼300 K and show semihard magnetic properties. The other two phases FeSe2 and β-FeSe exhibiting weaker magnetism are less known for their magnetic properties. All these phases are prone to surface oxidation despite surface passivation, and its effect on the magnetic moment will be pronounced for the phases with weak magnetization such as FeSe2 and β-FeSe.
