Temperature stability of field induced anisotropy in soft ferromagnetic Fe,Co-based amorphous and nanocomposite ribbons
نویسندگان
چکیده
The temperature stability of field induced uniaxial anisotropy KU was investigated by thermomagnetic treatments of Co1−xFex 89Zr7B4 amorphous ribbons after field annealing below and above the crystallization temperature. We conclude: 1 Field annealing treatments are necessary to properly investigate the temperature stability of KU, 2 KU of field crystallized alloys exhibit improved temperature stability relative to alloys remaining amorphous after field annealing, and 3 larger KU is obtained for field crystallization treatments as compared to zero-field crystallization followed by field reannealing. Field crystallization may be required for elevated temperature applications when field induced anisotropy is critical for performance. © 2009 American Institute of Physics. DOI: 10.1063/1.3068547

Composition dependence of field induced anisotropy in ferromagnetic „Co,Fe...89Zr7B4 and „Co,Fe...88Zr7B4Cu1 amorphous and nanocrystalline ribbons
The composition dependence of field induced anisotropy KU of field annealed soft ferromagnetic Co1−xFex 89Zr7B4 and Co1−xFex 88Zr7B4Cu1 amorphous and amorphous/nanocrystalline “nanocomposite” melt spun ribbons is investigated. With the exception of the highest Co-containing alloys x 0.10 , the observations are discussed in terms of a superposition of directional pair ordering of Fe,Co atoms and...
متن کاملIntroducing and investigating structural and magnetic properties of ribbons Co68.5-xFe4WxSi16.5B11 (x = 0.8, 2) in amorphous and crystalline states
In this study, for the first time, cobalt base ribbons were made by adding two different amounts of tungsten with Co67.7Fe4W0.8Si16.5B11 and Co66.5Fe4W2 Si16.5B11 compounds by melt spinning in the water. The pattern of X-ray diffraction taken from these ribbons shows that these magnetic ribbons are amorphous. By using thermal analysis curves, taken from the ribbons, crystallization temperature...

In contrast with amorphous alloys, nanocrystalline soft magnetic materials show improved thermal stability and higher soft magnetic properties. The nanocrystalline soft magnetic composites are usually fabricated by partially crystallizing from parent amorphous alloys. This paper reports our experimental observation on the sequence of crystallization in metallic glass under a high magnetic field...

Transmission electron microscopy study of large field induced anisotropy (Co1−xFex)89Zr7B4 nanocomposite ribbons with dilute Fe-contents
Electron microscopy was employed to investigate the structure of magnetic field crystallized (Co1 xFex)89Zr7B4 alloys with only dilute Fe-contents (x=0, 0.025, 0.05, and 0.10). The x=0.025 and 0.05 alloys exhibit very large field induced anisotropies and multiple nanocrystalline phases (BCC, FCC, and HCP) surrounded by an intergranular amorphous phase. Correlation between the volume fraction cr...
