Amorphous and nanocrystalline materials for applications as soft magnets
TL;DR: In this paper, the authors summarize the recent developments in the synthesis, structural characterization, properties, and applications of amorphous and nanocrystalline soft magnetic materials, including: kinetics and thermodynamics, structure, microstructure, and intrinsic and extrinsic magnetic properties.

Bulk metallic glasses
TL;DR: In the last decade metallic glasses have regained considerable interest due to the fact that new glass-forming compositions have been found that have a critical cooling rate of less than 100 K/s and can be made glassy with dimensions of 1 cm or more as discussed by the authors.

Size dependence of specific power absorption of Fe3O4 particles in AC magnetic field
TL;DR: In this article, the specific absorption rate (SAR) values of aqueous suspensions of magnetite particles with different diameters varying from 7.5 to 416nm were investigated by measuring the time-dependent temperature curves in an external alternating magnetic field (80 kHz, 32.5 kA/m).

The exchange-spring magnet: a new material principle for permanent magnets
E. Kneller,R. Hawig +1 more
TL;DR: In this article, permanent magnets can be made of composite materials consisting of two suitably dispersed ferromagnetic and mutually exchange-coupled phases, one of which is hard magnetic in order to provide a high coercive field, while the other may be soft magnetic, just providing a high saturation J/sub s/, and should envelop the hard phase regions to prevent their corrosion.

Grain size dependence of coercivity and permeability in nanocrystalline ferromagnets
TL;DR: In this article, a series of crystallized ribbons of composition Fe/sub 74.5-x/Cu/sub x/Nb/sub 3/Si/sub 13.5/B/sub 9/ (x=0, 1 at) have been annealed between about 500 degrees C and 900 degrees C.

Grain structure and magnetism of nanocrystalline ferromagnets
TL;DR: Amorphous ribbons of composition Fe/sub 73.5,Cu/sub 1/Nb/sub 3/Si/sub 13.5/B/sub 9/ have been annealed above their crystallization temperature, which produces a homogeneous, ultrafine grain structure of alpha FeSi with typical grain diameters of 10-20 nm.
