Realization of Complex‐Shaped Magnetic Nanotubes with 3D Printing and Electrodeposition
Advanced Functional Materials, Volume 36, Issue 4, 12 January 2026.Complex‐shaped magnetic nanotubes were fabricated by coating three‐dimensional nanoscaffolds fabricated with focused electron beam induced deposition with a magnetic coating via electrodeposition. X‐ray magnetic microscopy and simulations revealed an azimuthal magnetic configuration within the nanotubes and pinning of domain walls at curved vertices ...

Small Science, Volume 6, Issue 1, January 2026.Large‐scale micromagnetic simulations show how disorder and grain boundaries control magnetization dynamics in iron‐oxide nanoflowers beyond the single‐domain regime. Two competing vortex‐reversal modes emerge, producing a coercivity maximum at their transition.

Incidence of the Brownian Relaxation Process on the Magnetic Properties of Ferrofluids
NanomaterialsFerrofluids containing magnetic nanoparticles represent a special class of magnetic materials due to the added freedom of particle tumbling in the fluids. We studied this process, known as Brownian relaxation, and its effect on the magnetic properties of

Comptes Rendus. Physique, 2005 A single crystal made of nanomagnets is a macroscopic quantum object. The first of this class to have been discovered is the so-called molecular complex Mn12-ac with a spin S=10 per molecule. With vanishingly small tunneling gaps this system opened the field of slow quantum dynamics (incoherent), with the study of interplays between classical and ...

Focus on artificial frustrated systems
New Journal of Physics, 2014 Frustration in physics is the inability of a system to simultaneously satisfy all the competing pairwise interactions within it. The past decade has seen an explosion of activity involving engineering frustration in artificial systems built using ...
