Exchange field penetration in Fe73.5Cu1Mo3Si12.5Al1B9 alloy

A simple method for determining the lattice parameter and chemical composition in ternary bcc-Fe rich nanocrystals

“…For example Borrego et al [2] and Zorkovská et al [3] in bcc Fe-Si-Al nanocrystals, Blázquez et al in bcc Fe-Co-Ge nanocrystals [4], Gómez-Polo et al [5], Borrego et al [6] and Zbroszczyk et al [7] in bcc Fe-Co-Si nanocrystals. In some other works, having the necessary data to determine the chemical composition, it is not reported due perhaps to the lack of a tool for this purpose (for example, [8] in bcc Fe-Si-Al and [9] in bcc Fe-Si-Ge nanocrystals). In previous works [10][11][12], we already employed these two techniques to approach the chemical composition of Fe-Si-Ge and Fe-Si-Al nanocrystals.…”

High frequency behaviours and Mössbauer study of field annealed FeCuNbSiB alloy ribbons

“…FINEMET type nanocrystalline alloys have been widely investigated due to their tremendous potential for applications [1,2] and their fundamental theoretical interests [3,4] immediately after the discovery of Fe 73.5 Si 13.5 B 9 Nb 3 Cu 1 . [5] Previous studies have shown that the appropriate heat treatment of this family of alloys can produce the homogeneous ultrafine grain structure of α-FeSi embedded in the amorphous matrix with a typical grain diameter of 10 nm.…”

“…[5] Previous studies have shown that the appropriate heat treatment of this family of alloys can produce the homogeneous ultrafine grain structure of α-FeSi embedded in the amorphous matrix with a typical grain diameter of 10 nm. [4,6] This will cause a drastic reduction in the magnitude of saturation magnetostriction and the intrinsic coercivity due to the exchange-coupling interaction of the nanograins, and thus leads to a considerable improvement of the soft magnetic properties. Many studies, including the effect of both the substitution of various elements [7−10] and heat treatment conditions, [9−12] have been conducted to develop FINEMET type alloys with remarkable soft magnetic properties.…”
