Hr. Zhai et al., INTERLAYER COUPLING IN TM (FE, FECO, FECONI) CU MULTILAYERS STUDIED WITH FMR MEASUREMENTS/, Journal of magnetism and magnetic materials, 144, 1995, pp. 525-526
Spin wave resonance modes were observed in Fe(22 Angstrom)/Cu(d(Cu) An
gstrom) and FeCo(14 Angstrom)/Cu(d(Cu) Angstrom) multilayers by FMR me
asurements, which demonstrated that spin waves propagate through nonma
gnetic layers and that the multilayer film was like a single magnetic
system. In FeCoNi(15 Angstrom)/Cu(d(Cu) Angstrom) multilayers with Fe
buffer layers, a group of resonance peaks were observed in parallel ge
ometry.
