Magnetic properties of amorphous Co₀.₇₄Si₀.₂₆/Si multilayers with different number of periods
Two sets of [Co₀.₇₄Si₀.₂₆0.26(5 nm)/Si(s)]n amorphous films were prepared by magnetron sputtering: one in the form of multilayers with the Si spacer thickness s fixed at 3 nm, and the number of periods n varying from 1 to 10; and another one with only two periods and s varying from 3 to 24 nm (trila...

| description | Two sets of [Co₀.₇₄Si₀.₂₆0.26(5 nm)/Si(s)]n amorphous films were prepared by magnetron sputtering: one in the form of multilayers with the Si spacer thickness s fixed at 3 nm, and the number of periods n varying from 1 to 10; and another one with only two periods and s varying from 3 to 24 nm (trilayers). In both series, the Co₀.₇₄Si₀.₂₆0.26 layer thickness t was fixed at 5 nm. All the samples except the one with s = 24 nm demonstrate antiferromagnetic coupling. Their magnetic properties at room temperature were probed by magnetooptical transverse Kerr effect (MOTKE) and ferromagnetic resonance (FMR). The relative increase of the saturation magnetization Ms (for trilayers with respect to the one with s = 24 nm; for multilayers with respect to the single layer one) obtained from the FMR measurements was compared with the exchange coupling strength HAFJ obtained from the MOTKE studies. HAFJ and Ms dependencies vs n and s were found to be very similar to each other. Possible mechanisms of this similarity are discussed.
