Magnetic and anomalous magnetic viscosity in the bulk amorphous ferromagnet and partially amorphous ferromagnet

Publikováno v: Journal of Magnetism and Magnetic Materials. 321:3293-3299

A number of ferromagnetic Pr–Fe–Al alloys have been prepared by argon arc melting and quenching into a copper mould. The alloy of composition Pr 58 Fe 24 Al 18 is identified as being amorphous (bulk metallic glass or bulk amorphous ferromagnet),

The fluctuation field, H f , is a useful parameter for characterising any ferromagnetic material that displays hysteresis, as it is a measure of the thermally activated rate processes that govern magnetisation reversals. Anomalous magnetic viscosity,

A comparison of the magnetic properties of commercial HDDR powder with those of other commercial sintered rare-earth magnets

Autor: S J Collocott, J B Dunlop

Publikováno v: Journal of Physics D: Applied Physics. 30:1477-1482

Rare-earth permanent magnet motors are being used increasingly in electrical machines and modern production methods frequently require in situ magnetization of the magnets. Magnetic measurements have been performed on magnetically anisotropic powder

Magnetic properties of nanocomposite and materials with an excess of Fe

Autor: S J Collocott, P B Gwan, M. Jurczyk, J B Dunlop

Publikováno v: Journal of Physics D: Applied Physics. 29:2284-2289

Two-phase nanocomposite materials have been prepared by high-energy ball-milling (HEBM) (2:14:1 phase) (u = 0, 0.75, 1.5 or 3.0; y = 0 or 11.6 and z = 0 or 0.5) or (1:12 phase), with excess Fe and then annealing. Magnetic properties of materials cont

Spin-reorientations in DyFe10Cr2: A57Fe Mössbauer study

Autor: J. M. Cadogan, J. B. Dunlop, D. H. Ryan

Publikováno v: Hyperfine Interactions. 94:1951-1957

We have used57Fe Mossbauer spectroscopy carried out on a magnetically aligned powder sample of DyFe10Cr2 to investigate its magnetic structure at low temperatures. Previous susceptibility measurements by Stefanski [1] demonstrated the occurrence of a

Electron and X-ray diffraction techniques have been used to study the structure of polycrystalline C[sub 60]H[sub 36] with 10-15% C[sub 70]H[sub 36]. X-ray diffraction has shown that the molecular packing is body-centered cubic. Electron diffraction
