TLDR
In this paper, the authors present materials at the practical rather than theoretical level, allowing for a physical, quantitative, measurement-based understanding of magnetism among readers, be they professional engineers or graduate-level students.Abstract:
Introduction to Magnetic Materials, 2nd Edition covers the basics of magnetic quantities, magnetic devices, and materials used in practice. While retaining much of the original, this revision now covers SQUID and alternating gradient magnetometers, magnetic force microscope, Kerr effect, amorphous alloys, rare-earth magnets, SI Units alongside cgs units, and other up-to-date topics. In addition, the authors have added an entirely new chapter on information materials. The text presents materials at the practical rather than theoretical level, allowing for a physical, quantitative, measurement-based understanding of magnetism among readers, be they professional engineers or graduate-level students.read more

Synthesis and characterization of large colloidal cobalt particles.
Verónica Salgueiriño-Maceira,Miguel A. Correa-Duarte,Michael Farle,M. Arturo López-Quintela,Karl Sieradzki,Rodolfo E. Diaz +5 more
TL;DR: Large colloidal environmentally stable silica-coated cobalt particles were synthesized by combining the sodium borohydride reduction in aqueous solution and the Stöber method, explaining the superparamagnetic behavior of the spheres.

Effects of surface roughness and training on the twinning stress of Ni―Mn―Ga single crystals
Markus Chmielus,Katharina Rolfs,Robert C. Wimpory,Walter Reimers,Peter Müllner,Rainer Schneider +5 more
TL;DR: In this article, it was shown that different surface treatments in combination with repeated mechanical deformation experiments significantly reduce the twinning stress, regardless of whether or not electropolishing is used.
