TL;DR: The results demonstrate that an external static magnetic field of about 0.7 tesla is expelled from the volume of 119Sn foil as a result of the shielding by the H2S sample at temperatures between 4.7 K and approximately 140 K, revealing a superconducting state of H1S.
Journal ArticleDOI
Mössbauer spectroscopy and magnetic properties of hematite/magnetite nanocomposites
TL;DR: In this paper, a thermal reduction method has been developed to prepare magnetite/hematite nanocomposites and pure magnetite nanoparticles targeted for specific applications, and the relative content of hematite α-Fe2O3 and magnetite Fe3O4 nanoparticles in the product was ensured by maintaining proper conditions in the thermal reduction of α -Fe 2O3 powder in the presence of a high boiling point solvent.
