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

Preparation of magnetically susceptible polyacrylamide/magnetite beads for use in magnetically stabilized fluidized bed chromatography.
TL;DR: The PAM beads show excellent potential for use in MSFB chromatography and could be derivatized and activated for soybean trypsin inhibitor immobilization by a standard carbodiimide method, and the affinity separation oftrypsin from chymotrypsin was demonstrated.

Synthesis and characterization of magnetite nanoparticles coated with lauric acid
Javier Bustamante Mamani,Antonio J. Costa-Filho,Daniel Reinaldo Cornejo,Ernanni D. Vieira,Lionel Fernel Gamarra +4 more
TL;DR: In this paper, the synthesis of magnetic nanoparticles made from ferrous oxide through coprecipitation chemical process is reported, where the nanostructured material was coated with lauric acid and dispersed in aqueous medium containing surfactant that yielded a stable colloidal suspension.

Theoretical modelling of the effects of anisotropy and stress on the magnetization and magnetostriction of Tb0.3Dy0.7Fe2
David Jiles,J.B. Thoelke +1 more
TL;DR: In this paper, the Stoner-Wohlfarth model was applied to the Tb0.3Dy0.7Fe2 Alloy and the results showed that the magnetic moments of the domains are constrained by the anisotropy to lie along the directions within the crystal.

XRD, magnetic and Mössbauer spectral studies of nano size aluminum substituted cobalt ferrites (CoAlxFe2−xO4)
TL;DR: Aluminum substituted cobalt ferrites having particle size ∼10nm were prepared using aerosol route, which increases with annealing temperature The unit cell parameter ‘ a ’ and saturation magnetization decreases linearly with the increase of aluminum concentration This is due to the smaller ionic radius and the diamagnetic nature of the Al 3+, respectively Room temperature Mossbauer spectra of the samples annealed at 1200°C show broad sextets, which were fitted with different sextet, indicating different local environment of both tetrahedrally and octahed
