Abstract
The Fe56.8–72.5Zr5.9–11.6N13.8–31.6O1.2–3.4 films were prepared by magnetron deposition. The metastable structural and phase state, which was formed upon deposition, is represented by either mixed (nanocrystalline αFe(Zr,N) + amorphous) or amorphous structure. During subsequent annealing (300–600°C), it slightly shifts toward the stable state due to partial crystallization of the amorphous phase and precipitation of the secondary phases (Fe4N, Fe3N, and ZrO2). The grain structure of the films (grains 3–12 nm in size) is characterized by thermal stability. The relatively low saturation magnetization Ms (870–1400 G) of the films is explained by the presence of the amorphous phase and αFe(Zr,N) solid solution, which remain in the film structure after annealing at all temperatures. The stochastic domain structure is formed in all films under study due to exchange interaction between grains and clusters in the amorphous structure. The strong dependence of the magnetic structure on the phase state and grain structure of the films is demonstrated. The combination of low local magnetic anisotropy and the highest stochastic domain size predetermines the lowest coercive field of the films, which varies in a range of 1 to 50 Oe.
期刊介绍：
The Physics of Metals and Metallography (Fizika metallov i metallovedenie) was founded in 1955 by the USSR Academy of Sciences. Its scientific profile involves the theory of metals and metal alloys, their electrical and magnetic properties, as well as their structure, phase transformations, and principal mechanical properties. The journal also publishes scientific reviews and papers written by experts involved in fundamental, application, and technological studies. The annual volume of publications amounts to some 250 papers submitted from 100 leading national scientific institutions.
