Composite Materials Fabricated of Amorphous and Nanocrystalline Metallic Powders

Amorphous and Nanocrystalline Soft Magnetic Materials

Annealing of amorphous precursor alloys, with compositions (Fe,Co!88M7B4Cu1 ~M5Zr, Nb, Hf!, above their primary crystallization temperature results in the nanocrystallization of the ferromagnetic a8-FeCo phase. This work describes results of the characterization of these alloys, including morphological and chemical stability of the a8-FeCo phase, examination of alloy compositions, and developme...

Thermopower of nanocrystalline germanium/hydrogenated amorphous silicon composite thin films

Amorphous and nanocrystalline materials for applications as soft magnets

This review seeks to summarize the recent developments in the synthesis, structural characterization, properties, and applications in the ®elds of amorphous, bulk amorphous, and nanocrystalline soft magnetic materials. Conventional physical metallurgical approaches to improving soft ferromagnetic properties have relied on the optimization of chemical and microstructural features. Within the las...

Characterization of Nanocrystalline Si-MCMB Composite Anode Materials

Amorphous and Nanocrystalline Soft Magnets

− The article surveys amorphous and nanocrystalline alloys for soft magnetic applications. Both materials have much in common starting from their way of production and ranging over to the key factors which determine their properties. Thus, the magneto-crystalline anisotropy is randomly fluctuating on a scale much smaller than the domain wall width and, as a consequence, is averaged out by excha...
