摘要: Abstract The magnetic properties of ultrathin Fe (1 0 0) films were investigated by polarized neutron reflectometry (PNR). with different thicknesses from 1 to 3 nm prepared Molecular Beam Epitaxy (MBE) on a V buffer layer, which was deposited MgO single crystal. In order avoid oxidation the covered capping layers. During preparation process growth monitored low-energy electron diffraction (LEED) and Auger spectroscopy (AES). Combining information obtained PNR X-ray (XRR), layers determined precisely. From measurements absolute value magnetization could be fitting spin-up spin-down reflectivities separately. moments show perfect linear dependence film thickness t . line intersects abscissa at =(0.1±0.01) nm. This means that two V/Fe interfaces up as constant reduction moment equal an bulk layer
