ABSTRACTThe interlayer exchange coupling has been studied in two trilayer structures:(a) 5.7Fe/5Cu/1FecCu1-c/5Cu/10Fe(001), where c=0.0, 0.1, 0.2, 0.45 0.60(b) 5.7Fe/5Cu/1CrcCu1-c/5Cu/10Fe(001), where c=0.1, 0.45, 0.8 and 1.0.The intention of these studies was to identify the role of Fe and Cr atoms in the alloyed FecCu1-c and CrcCu1-c layers on the direct interlayer coupling which is facilitated by the Cu valence electrons. FMR, BLS and MOKE studies were used to determine the interlayer exchange coupling. Mossbauer spectroscopy was used to identify the magnetic state of the Fe atoms in the alloyed layer. The results showed that the presence of foreign atoms inside the Cu spacer significantly decreased the bilinear antiferromagnetic coupling between the Fe layers. In the low concentration limit the Fe and Cr atoms behaved in a similar manner. A significant difference was found in the high concentration limit where the Fe atoms start to be partially magnetically ordered.

ABSTRACTThe photothermally modulated ferromagnetic resonance (PM-FMR) has been successfully applied to investigate the position dependence of FMR properties of wedged Fe-samples. The temperature dependence of the surface contribution to the anisotropy could be separated from the demagnetizing field with high accuracy. The oscillating first order interlayer exchange coupling and the anisotropy fields of the Fe-films of a Fe/Cr-wedge/Fe-sample (3.0/0.7–2.8/2.0 nm) were deduced from PM-FMR spectra.
