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...
متن کاملThermal, Magnetic, and Structural Characterization of the Crystallization Kinetics of Amorphous Soft Magnetic Materials
Introduction An understanding of the crystallization kinetics of magnetic amorphous alloys is of scientific interest for two important reasons. First, for an alloy that exhibits excellent magnetic properties in its amorphous phase, the crystallization kinetics represent the limit at which these properties begin to deteriorate. Therefore, thermal stability determines the magnetic stability of th...
متن کاملAnomalous magnetic viscosity in bulk-amorphous materials
The demagnetization processes and the magnetic viscosity have been studied on a bulk-amorphous Nd 60 Fe 30 Al 10 rod at room temperature. Many unique magnetic properties have been found in this novel hard magnetic material. A clear hysteresis was present on the minor loops, though the total and irreversible susceptibilities exhibited single-phase magnet behavior. A signi"cant magnetic viscosity...
متن کاملGMI Effect of Ultra-Soft Magnetic Soft Amorphous Microwires
In this paper we experimentally studied GMI effect and soft magnetic behavior of Co-rich microwires. Correlation between magnetoelastic anisotropy and magnetic field dependences of diagonal and off-diagonal impedance components are observed. Low field GMI hysteresis, explained in terms of magnetoelastic anisotropy of microwires, has been suppressed by the bias current.
متن کاملAmorphous 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...
