Microstructure and magnetic properties of amorphous and nanocrystalline Fe80M7B12Cu1 (M - Nb, Ti or Mo) alloys

Magnetic and structural characterization of Mo-Hitperm alloys with different Fe/Co ratio

“…Therefore, the thermal stability of the amorphous alloys as well as that of the nanocrystalline two-phase systems are reduced as the Co content in the alloy increases, as previously reported [16,17]. However, compared with similar Co-free alloys the presence of Co decreases the thermal stability of the amorphous alloys but increases that of the nanocrystalline ones [7][8][9][10][11].…”

“…Many studies on Hitperm FeCoZrB and FeCoNbB alloys have been reported [1][2][3][4][5] but, more recently, FeCoMoB alloys have been paid increasing attention [6]. Mo addition to Fe alloys delays the iron oxidation in this system and affects the thermal stability and magnetic properties of these amorphous alloys, with a significant lowering of the Curie temperature [7][8][9][10][11][12].…”

Composition dependence of Curie temperature and microstructure in amorphous Fe–Co–Mo–Cu–B metallic glasses

“…Although good thermal stability in a very wide temperature range along with an increase in the saturation magnetization were achieved, the soft magnetic behaviour deteriorates due to the increase of material magnetostriction. Many studies on FeCoZrB [1] and FeCoNbB [1,2] alloys have been reported but fewer attention has received the FeMoB [3,4] system. Mo addition to Fe,Co alloys considerably delays the iron oxidation in this system and affects the thermal stability and magnetic properties of these amorphous alloys, with a significant lowering of the Curie temperature.…”

Low Field Magnetic Properties of FeCo-Based Alloys

“…Along with classical compositions [1], novel structures containing Mo [2], Co [3], or more recently also combination of these two [4], are of close interest. Partial replacement of Fe atoms by Co in such alloys leads to both, changes in the structure, and to the increase of magnetic inductions at elevated temperatures.…”
