| الوصف: | We investigated the magnetic properties of Co2MnSn Heusler alloy films, which were grown by alternate deposition of monoatomic Co, sub-atomic Mn, and sub-atomic Sn layers with electron-beam evaporation, by means of SQUID magnetometory and 119Sn Mossbauer spectroscopy. The Mossbauer spectra sensitively showed that the local magnetism at the Sn sites in the Co2MnSn films depends on the substrate temperature. We also measured the tunnel magnetoresistance of the magnetic tunnel junctions with a Co2MnSn/MgO/Co2MnSn structure. The magnetoresistance of the junction where the magnetic circumstances at the Sn sites are relatively uniform is measured to be 2 % at 5 K at the present stage. |
