Fabrication of bulk nanocomposite magnets via severe plastic deformation and warm compaction,
(American Institute of Physics, 2010-03-10)
We demonstrate that a SmCo/FeCo based hard/soft nanocomposite material can be fabricated by distributing the soft magnetic α-Fe phase particles homogeneously in a hard magnetic SmCo phase through severe plastic deformation. ...
Anisotropic nanostructured magnets by magnetic-field-assisted processing
(American Institute of Physics, 2010-04-15)
It has been a great challenge to produce anisotropic nanocrystalline bulk magnets. In this paper, we report our recent work in preparing anisotropic bonded magnets consisting of SmCo5 nanocrystalline particles. The work ...
Effects of particle size and composition on coercivity of Sm–Co nanoparticles prepared by surfactant-assisted ball milling
(American Institute of Physics, 2010-04-15)
The correlation between the recoil loop openness and the activation volume has been studied for the SmCo5/α-Fe nanocomposite powder material prepared by mechanical alloying. The α-Fe phase content in the nanocomposite ...
Effect of thermal fluctuations on the recoil loops of SmCo5[subscript]/Fe nanocomposite system
(American Institute of Physics, 2009-02-13)
The correlation between the recoil loop openness and the activation volume has been studied for the SmCo5/α-Fe nanocomposite powder material prepared by mechanical alloying. The α-Fe phase content in the nanocomposite ...
First-principles prediction of enhanced magnetic anisotropy in FeCo alloys
(American Institute of Physics, 2008-02-04)
The structural, electronic, and magnetic properties of FeCo alloys were studied by first-principles calculations. It has been found that the alloys prefer chemically noncubic geometries in a wide composition range. This ...
Mechanism of the anomalous temperature dependence of coercivity in Sm(Co,Fe,Cu,Zr)[subscript]z high-temperature magnets
(American Institute of Physics, 2006-01-24)
Coercivity mechanism of the precipitation-hardened Sm(Co,Fe,Cu,Zr)z high-temperature magnets was found to vary with temperature by measurements of reversible magnetization. The magnetization reversal is mainly controlled ...
