Journal ArticleDOI
Magnetic multilayers on nanospheres
Manfred Albrecht,Guohan Hu,I. L. Guhr,Till C. Ulbrich,Johannes Boneberg,Paul Leiderer,Günter Schatz +6 more
TL;DR: In this article, a new class of magnetic material with a unique combination of remarkable properties is presented, which reveals a uniform magnetic anisotropy with an unexpected switching behavior induced by their spherical shape.
Journal ArticleDOI
Magnetization reversal in a novel gradient nanomaterial.
T. C. Ulbrich,Denys Makarov,Guohan Hu,I. L. Guhr,Dieter Suess,Thomas Schrefl,Manfred Albrecht +6 more
TL;DR: The deposition of Co/Pd multilayer films onto self-assembled particle arrays with particle sizes down to 50 nm leads to pronounced curvature-induced physical properties, offering new opportunities in the functionalization of magnetic nanostructures.
Journal ArticleDOI
Magnetic dot arrays with multiple storage layers
TL;DR: In this paper, an approach to increase the data storage density of magnetic recording was investigated wherein dot arrays are combined with multiple magnetic storage layers. But it was found that even for thick spacer layers a weak magnetostatic coupling of the storage layers is present preferring ferromagnetic alignment of the layers.

Patterned multilevel perpendicular magnetic recording media
TL;DR: A patterned perpendicular magnetic recording medium has magnetic islands that contain stacks of individual magnetic cells to provide multilevel recording as discussed by the authors, where each cell in an island is formed of a material or set of materials to provide the cell with perpendicular magnetic anisotropy and is a single magnetic domain.
Journal ArticleDOI
Magnetic and recording properties of Co/Pd islands on prepatterned substrates
Guohan Hu,Thomas Thomson,Manfred Albrecht,Margaret Evans Best,Bruce D. Terris,Charles T. Rettner,Simone Raoux,Gary M. McClelland,Mark W. Hart +8 more
TL;DR: Magnetically isolated single domain islands with perpendicular anisotropy have been prepared by depositing Co/Pd multilayer films on prepatterned sub-50 nm SiO2/Si islands as discussed by the authors.
