“…Many recent studies [1][2][3][4] have demonstrated that the magnetic properties of NiFe and CoFe layers differ from those in bulk samples of the same composition for layer thicknesses below around 20 nm. The observed changes are a strong function of the seed and capping layer.…”

NOLs were added at different positions to study the effects of NOL on s of CoFe FL. All s of CoFe FL change from negative to positive and its absolute value also increases significantly with CoFeO x related NOL added below. Our s and surface roughness results indicated that the structure of the film not the roughness dominates s of ultrathin FL in SVs.

“…This interest is motivated by the fact that magnetic properties of these types of structures are the real technological issues in mass production of spin-valve read heads and in other important applications like magnetic random access memories and spintronic devices. 1 2 Many recent studies [3][4][5][6][7][8][9] have demonstrated that the magnetic properties of NiFe and CoFe differ from those in bulk samples of the same composition for layer thickness below around 20 nm.

Ferromagnetic monolayers Co90Fe10 thin films with individual layer thicknesses 2, 6, and 8 nm were grown on thermally oxidized Si substrate and magnetic properties of these were investigated with Ferromagnetic resonance (FMR) technique at room temperature. The magnetoresistance (MR) of the samples were measured as a function of applied DC magnetic field and the thickness dependence of the MR was plotted. The FMR spectra were recorded for both parallel and perpendicular geometry. The X-band (9.5 GHz) FMR spectra and resonance field of samples were analyzed and fitted theoretically by using the Landau-Lifshits dynamic equation of motion for magnetization with the Bloch-Bloembergen type damping term. The computer programs have been written to extract the effective magnetization (M), g-values and spin-spin relaxation time (T2) fitting parameters. The thickness dependence of magnetic parameters has been obtained from experimental data by mean of a theoretical model.
