Journal ArticleDOI
De Magnete et Meteorite: Cosmically Motivated Materials
Laura H. Lewis,Frederick E. Pinkerton,N. Bordeaux,A. Mubarok,Eric Poirier,Joseph I. Goldstein,Ralph Skomski,Katayun Barmak +7 more
TL;DR: In this paper, the permanent magnetic properties of bulk tetrataenite derived from the meteorite NWA 6259 are quantified, and the measured magnetization approaches that of Nd-Fe-B (1.42 T) and is coupled with substantial anisotropy (1 0-1.3 MJ/m 3) that implies the prospect for realization of technologically useful coercivity.
Journal ArticleDOI
Spatial texture distribution in thermomechanically deformed 2–14–1-based magnets
TL;DR: In this paper, the authors explored alternative techniques for the measurement of the bulk texture of permanent magnets using both hard x-ray diffraction and transmission synchrotron X-ray diffusion experiments.
Journal ArticleDOI
Exchange anisotropy in the nanostructured MnAl system
Félix Jiménez-Villacorta,J. L. Marion,T. Sepehrifar,Maria Daniil,Matthew A. Willard,Laura H. Lewis +5 more
TL;DR: In this article, the authors reported the achievement of exchange anisotropy magnitude in a nanostructured Mn55Al45 alloy fabricated by rapid solidification with large exchange bias values (HE ≈ 13 kOe at 10 K) and a blocking temperature of TB ∼ 95 K.
Journal ArticleDOI
Bulk and near-surface magnetic properties of FeRh thin films
Y. Ding,Dario Arena,J. Dvorak,Mannan Ali,Christian J. Kinane,Christopher H. Marrows,B. J. Hickey,Laura H. Lewis +7 more
TL;DR: In this article, the presence of the anticipated magnetostructural phase transition from antiferromagnetic to ferromagnetism at ∼350K was confirmed by superconducting quantum interference device and magneto-optic Kerr effect magnetometry.
Journal ArticleDOI
Magnetism-Structure Correlations during the ε→τ Transformation in Rapidly-Solidified MnAl Nanostructured Alloys
Félix Jiménez-Villacorta,J. L. Marion,John T. Oldham,Maria Daniil,Matthew A. Willard,Laura H. Lewis +5 more
TL;DR: Magnetic and structural aspects of the annealing-induced transformation of rapidly-solidified Mn55Al45 ribbons from the as-quenched metastable antiferromagnetic e-phase to the target ferromagnetic L10 τ-phase are investigated in this paper.
