From Fe3Si towards Fe3Ge in Finemet-like nanocrystalline alloys: Mössbauer spectroscopy
(Elsevier Science, 2007-02-01)
Nanocrystalline Finemet-type ribbons with different Si/Ge ratio [Fe73.5Si13.5-xGexNb 3B9Cu1 (x = 7, 8, 10 and 13.5)] were studied by means of Mössbauer spectroscopy and X-ray diffraction. The trend to form the non-stoichiometric ...
Domain imaging in FINEMET ribbons
(Elsevier Science, 2010-09)
The magnetization behaviour of a ferromagnetic material depends on its domain structure, which in turn is largely determined by magnetic anisotropies. In this work, domain patterns were observed by a quite forgotten but ...
Dynamic coercivity of Mo-doped FINEMETs
(Elsevier Science, 2011-05)
The structure and the dc magnetic behavior of FINEMET-type alloys doped with molybdenum have been recently reported. Most commercial applications of these materials are, however, not at dc but at high magnetizing frequencies. ...
Structural and magnetic study of Mo-doped FINEMET
(Elsevier Science, 2011-02)
In this paper, a study of the structural and the magnetic correlation of the crystalline and amorphous phases in the nanocrystalline system Fe73.5Si13.5B9Nb3−xMoxCu1 (x=0, 1.5, 2, 3) was made. By means of Mössbauer ...
Magnetoimpedância em Filmes Finemet/Metal/Finemet
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2004-10-01)
The magnetoimpedance effect (MI) in sandwiched thin films of the FeCuNbSiB/Cu produced by Magnetron Sputtering is studied using HP4396B impedance analyzer in the
frequency range 100kHz-1,8GHz. The samples were produced ...
FINEMET type alloy without Si: Structural and magnetic properties
(Elsevier Science, 2008-05)
Magnetic and structural properties of a Finemet type alloy (Fe73.5Ge15.5Nb3B7Cu1) without Si and high Ge content were studied. Amorphous material was obtained by the melt spinning technique and was heat treated at different ...

Improving soft magnetic properties in FINEMET-like alloys. A study
(Elsevier, 2014-11)
An approach to improve the soft magnetic properties of nanocomposite FINEMET-like alloys is presented by the study of the theoretical behavior of the coercive field with the crystallized fraction, Hc(mcr), curves where the ...
High performance of low cost soft magnetic materials
(Springer Verlag Berlín, 2011-12)
The consistent interest in supporting research and development of magnetic materials during the last century is revealed in their steadily increasing market. In this work, the soft magnetic nanocrystalline FINEMET alloy ...
