Abstract
Some results concerning the influence of the composition and thickness of NbCu spacer layer on the microstructure and magnetic properties of multilayer [NdFeB/(NbCu)]×n[NdFeB/(NbCu)]×n films, in view of their utilization for manufacturing the thin film permanent magnets are presented. A comparison between the microstructure and magnetic properties of NdFeB single layer and [NdFeB/(NbCu)]×n[NdFeB/(NbCu)]×n multilayer is also presented. The multilayer [NdFeB/(NbCu)]×n[NdFeB/(NbCu)]×n thin films with the thickness of the NdFeB layer of 180 nm and the thickness of the NbCu spacer layer of 3 nm, exhibit good hard magnetic characteristics such as coercive force HcHc of about 1510 kA/m and the remanence ratio Mr/MsMr/Ms of about 0.8.
