Аннотация: The standing spin wave spectra of Ni0.8Fe0.2(1000-3000 Angstrom)/(Dy1-xCox (700 Angstrom) bilayer exchange-biased films with two different (precompensation Dy0.2Co0.8 and postcompensation Dy0.3Co0.7) compositions of the hard magnetic layer are analyzed. Measurements are performed at room temperature. It is found that the effective Показать полностьюmagnetic layer thickness (d(eff) = d(0) +/- Deltad), which determines the wave vectors of the first modes in the spectrum, differs from the d(0) value specified in film technology. The sign of \Deltad\ similar to 500 Angstrom is governed by the composition of the DyCo hard magnetic layer. (C) 2001 MAIK "Nauka/Interperiodica".
