摘要：
Both Fe-Pt cluster/Fe-Co film and Fe-Co cluster/Fe-Pt film laminated hybrids have been prepared by combination of a plasma-gas-cluster-deposition and a helicon-plasma sputter-deposition and studied by X-ray diffraction and magnetization measurements. In Fe-Pt cluster/Fe-Co film laminated hybrids, M-S increases, while H-C and BHMAX monotonically decrease with the Fe-Co film thickness. In Fe-Co cluster/Fe-Pt film aminated hybrids, M-S, H-C and BHMAX increase with the Fe-Co cluster layer thickness in comparison with those of simple Fe-Pt films. However, the remarkable improvement of their hard magnetic properties cannot be attained in these laminated hybrids owing to both the low packing density of Fe-Co clusters and the difficulty in the diffusion-control of Fe and Co atoms from Fe-Co to Fe-Pt layers.
