Artificial spin ice systems offer a promising platform to study the motion of emergent magnetic monopoles, but controlled nucleation of monopoles is challenging. Here the authors demonstrate controlled injection and propagation of emergent monopoles

The rare-earth-free MnAlC alloy is currently considered a very promising candidate for permanent magnet applications due to its high anisotropy field and relatively high saturation magnetization and Curie temperature, besides being a low-cost materia

Publikováno v: Beilstein Journal of Nanotechnology, Vol 6, Iss 1, Pp 1319-1331 (2015)

Iron nanostructures grown by focused electron beam induced deposition (FEBID) are promising for applications in magnetic sensing, storage and logic. Such applications require a precise design and determination of the coercive field (HC), which depend

Cylindrical magnetic nanowires with large transversal magnetocrystalline anisotropy have been shown to sustain non-trivial magnetic configurations resulting from the interplay of spatial confinement, exchange, and anisotropies. Exploiting these pecul

Magnetic flux closure in mutant magnetotactic bacteria elucidates a key signature of magnetofossils

Autor: Matthieu Amor, Christiphe Gatel, Julie Carlut, Etienne Snoeck, Ingrid Marie Andersen, Ramon Egli, Juan Wan, Arash Komeili

Magnetotactic bacteria (MTB) produce single- or multi-stranded chains of magnetic nanoparticles that contribute to the magnetization of sedimentary rocks. Their magnetic fingerprint can be detected in ancient geological samples, and serve as a unique
