Comparison of interface structure of BCC metallic (Fe, V and Nb) films on MgO (100) substrate

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

Resonant electronic states and I-V curves of Fe/MgO/Fe(100) tunnel junctions

The bias dependence of the tunnel magnetoresistance TMR of Fe/MgO/Fe tunnel junctions is investigated theoretically with a fully self-consistent scheme that combines the nonequilibrium Green’s-function method with density-functional theory. At voltages smaller than 20 mV the I-V characteristics and the TMR are dominated by resonant transport through narrow interface states in the minority-spin ...

Interface Fe magnetic moment enhancement in MgO/Fe/MgO trilayers

Study of magnetoresistance of epitaxial magnetite films grown on vicinal MgO „100... substrate

The magnetoresistance sMRd studies of magnetite thin films deposited on vicinal MgO substrates show an enhanced MR along the miscut direction as compared to the direction perpendicular to it. The MR anisotropy increases with the decrease in temperature and peaks at the Verwey transition. The increase in magnetoresistance and anisotropy behavior is attributed to the formation of a greater number...

Interface structure and surface morphology of (Co, Fe, Ni)/Cu/Si(100) thin films

We have examined bilayer Co/Cu, Fe/Cu, and Ni/Cu films deposited by molecular-beam epitaxy on hydrogen-terminated @100# silicon substrates. The magnetic metal/copper interface was examined by atomic resolution transmission electron microscopy and compared with the surface morphology as depicted by atomic force microscopy. The general orientation relationships across the magnetic metal/copper in...
