Coccolithophores, marine calcifying phytoplankton, are important primary producers impacting the global carbon cycle at different timescales. Their biomineral structures, the calcite containing coccoliths, are among the most elaborate hard parts of any organism. [...]

An approach to compute the polarizability tensor of magnetic nanoparticles having general ellipsoidal shape is presented. We find a surprisingly excellent quantitative agreement between calculated and experimental magneto-optical spectra measured in the polar Kerr configuration from nickel nanodisks of large size (exceeding 100 nm) with circular and elliptical shape.

3 p, 409.4 KB Continuously graded anisotropy in single (Fe53Pt47)100−xCux films / Zha, Chaolin (Kungl. Tekniska högskolann. Materialfysik) ; Dumas, Randy K. (University of Gothenburg. Department of Physic) ; Fang, Yeyu (Kungl. Tekniska högskolann. Materialfysik) ; Bonanni, Valentina (Kungl. Tekniska högskolann. Materialfysik) ; Nogués, Josep (Institut Català de Nanociència i Nanotecnologia) ; Aakerman, Johan (Kungl. Tekniska högskolann. Materialfysik) ; American Physical Society
We report on continuously graded anisotropy. During deposition, a compositional gradient is achieved by varying the Cu concentration from Cu-rich (Fe53Pt47)70Cu30 to Cu-free Fe53Pt47. The anisotropy gradient is then realized after annealing using the composition dependence of the low-anisotropy (A1) to high-anisotropy (L10) ordering temperature. [...]
