We investigated coercivity, total losses and complex permeability of sintered Fe-Co powder cores to detect magnetization processes performing in ac magnetic field. The Fe-Co solid solution alloy powders with 50:50 wt% ratio were prepared by 1, 15, and 20 h alloyed mixture of pure chemical elements in planetary ball mill. The resulting powder was subsequently sintered into a disk form. The compaction was performed at a pressure of 800 MPa for 5 min at temperatures of 400•

Представлено експериментальні результати та літературні дані стосовно структурно-фазового стану, магнетотранспортних і магнетних властивос-тей плівок пермалою, одержаних різними методами. Проаналізовано вплив умов одержання на структурно-фазовий стан плівкових зразків. Показано, що в тонких плівках пермалою виявляється анізотропний маг-нетоопір, величина якого в середньому становить 3-4% за кімнатної тем-ператури. Одержано розмірні, концентраційні та температурні залежнос-ті анізотропного магнетоопору і коерцитивности.Ключові слова: плівковий стоп, магнетоопір, магнетна анізотропія, коер-цитивність, поле наситу.Представлены экспериментальные результаты и литературные данные, относящиеся к структурно-фазовому состоянию, магниторезистивным и магнитным свойствам плёнок пермаллоя, полученных различными мето-дами.

Abstract. Nanocrystalline Fe 100-x Al x powders (x= 25, 30, 34 and 40 at %) were prepared by the mechanical alloying process using a vario-planetary high-energy ball mill for a milling time of 35 h. The formation and physical properties of the alloys were investigated as a function of Al content by means of X-ray diffraction, scanning electron microscopy (SEM), energy dispersive X-ray and Mössbauer spectroscopy. For all Fe 100-x Al x samples, the complete formation of bcc phase was observed after 35 h of milling. As Al content increases, the lattice parameter increases, whereas the grain size decreases from 106 to 12 nm. The powder particle morphology for different compositions was observed by SEM. The Mössbauer spectra were adjusted with a singlet line and a sextet containing two components. The singlet was attributed to the formation of paramagnetic A2 disordered structure rich with Al. About the sextet, the first component indicated the formation of Fe clusters/ Fe-rich phases; however, the second component is characteristic of disordered ferromagnetic phase.
