Journal ArticleDOI
Exchange coupling and recoil loop area in Nd2Fe14B nanocrystalline alloys
TL;DR: In this paper, the recoil behavior of nanocrystalline materials based on Nd2Fe14B was investigated and the onset of recoil hysteresis, or attainment of appreciable area of the recoil loop was determined and followed as a function of the reverse applied magnetic field.
Journal ArticleDOI
Effect of annealing on magnetic exchange coupling in CoPt/Co bilayer thin films
TL;DR: In this paper, a model of thin film CoPt/Co bilayers was used to investigate the relationship between microstructure and exchange coupling in two-phase nanocomposite permanent magnets.
Journal ArticleDOI
Intrinsic magnetic properties of L10 FeNi obtained from meteorite NWA 6259
Eric Poirier,Frederick E. Pinkerton,Robert C. Kubic,Raja K. Mishra,N. Bordeaux,A. Mubarok,Laura H. Lewis,Joseph I. Goldstein,Ralph Skomski,Katayun Barmak +9 more
TL;DR: In this article, the magnetic properties of tetragonal L10 FeNi have been characterized using specimens found in nickel-iron meteorites, and the magnetic structure was modeled as a superposition of the three orthonormal uniaxial variants.
Journal ArticleDOI
Anisotropic magnetocaloric response in AlFe2B2
Radhika Barua,B.T. Lejeune,Liqin Ke,George C. Hadjipanayis,Eugene M. Levin,Eugene M. Levin,R. W. McCallum,Matthew J. Kramer,Laura H. Lewis +8 more
TL;DR: In this article, the magnetocaloric response of the intermetallic layered AlFe2B2 compound along the principle axes of the orthorhombic cell was carried out using aligned plate-like crystallites with an anisotropic growth habit.
Journal ArticleDOI
Functionalization-induced improvement in magnetic properties of Fe3O4 nanoparticles for biomedical applications
Dattatri Nagesha,Brian D. Plouffe,Minh Phan,Laura H. Lewis,Srinivas Sridhar,Shashi K. Murthy +5 more
TL;DR: In this paper, an increase in the magnetic size of the nanoparticle core induced by the dopamine ligand exchange process was reported. But, the results are consistent with an increase of the size and phase of the particles, and are tentatively attributed to surface bonding effects.
