Some Magnetic Properties of Thin Films Prepared from Fe-(M-NO-Si-B (M=Cu, Ag, Pt, Pd) Alloys

Saturation magnetic induction, B$\text{}_{s}$, and coercive field, H$\text{}_{c}$, have been studied upon annealing in films flash evaporated from Fe$\text{}_{73.5}$M$\text{}_{1}$Nb$\text{}_{3}$Si$\text{}_{13.5}$B$\text{}_{8}$ alloys. The changes in B$\text{}_{s}$ significantly diverged at increasing annealing temperature, T$\text{}_{a}$, and did not indicate any formation of ultrafine grain phase in the films. H$\text{}_{c}$ measured as an angular function in the plane of the films revealed oscillations due to weak in-plane anisotropy. The coercivity increased in the course of annealing at increasing T$\text{}_{a}$, while the in-plane anisotropy decreased at the same time.
