Magnetic Damping in Polycrystalline Thin-Film Fe − V Alloys
Monika Arora,Erna Krisztina Delczeg-Czirjak,Grant Riley,Grant Riley,Thomas J. Silva,Hans T. Nembach,Hans T. Nembach,Olle Eriksson,Justin M. Shaw +8 more
TL;DR: In this article, the authors report on the magnetic damping properties of polycrystalline thin films that are deposited at room temperature and show that exceptionally low values of the damping parameter can be maintained over the majority of this range, with a minimum damping at approximately 15%--20% $\mathrm{V}$ concentration.
Journal ArticleDOI
Transverse and longitudinal second-harmonic magneto-optic Kerr effect from Ni/sub 81/Fe/sub 19/ thin film structures
TL;DR: In this paper, the second harmonic magneto-optic Kerr effect was measured in both transverse and longitudinal geometries from Ni/sub 81/Fe/sub 19/ films.
Journal Article
Mode- and Size-Dependent Landau-Lifshitz Damping in Magnetic Nanostructures
TL;DR: A strong dependence of the effective damping on the nanomagnet size and the particular spin-wave mode that can be explained by the theory of intralayer transverse-spin pumping is demonstrated, with serious implications for the performance of nanoscale spintronic devices such as spin-torque-transfer magnetic random access memory.
Proceedings ArticleDOI
Magneto-optical Kerr effect probed using ultrafast high-order harmonic EUV light
Chan La-o-vorakiat,Mark E. Siemens,Justin M. Shaw,Hans T. Nembach,Stefan Matthias,Roman Adam,Claus M. Schneider,Martin Aeschlimann,Thomas J. Silva,Margaret M. Murnane,Henry C. Kapteyn +10 more
TL;DR: In this paper, tabletop high harmonics were used to detect the EUV transverse magneto-optical Kerr effect from a permalloy sample, and large asymmetries were measured around the M absorption edges of Fe (54eV) and Ni (67eV).
Journal ArticleDOI
Nonlinear optical investigations of magnetic heterostructures (invited)
TL;DR: In this paper, the second-harmonic magneto-optic Kerr effect investigations of magnetic heterostructures were performed and it was shown that the addition of 2 nm Co layer between Cu and Ni81Fe19 increases the magnetic signature in the secondharmonic intensity by more than a factor of two.
