Two optimized strategies were successfully established to develop biomolecule-based magnetic nanoassemblies. Streptavidin-coated and amine-coated magnetic nanoparticles were chosen as model scaffolds onto which double-stranded DNA and human immunoglobulin G were specifically conjugated in succession, using biotin-streptavidin interaction or covalent cross-linkers. The success of this study open...

A parallel finite element micromagnetics package has been implemented, which is highly scalable, easily portable and combines different solvers for the micromagnetic equations. The implementation is based on the standard Galerkin discretization on tetrahedral meshes with linear basis functions. A static energy minimization, a dynamic time integration and the nudged elastic band method have been...

This review is dedicated to summarizing the recent research on vortex dynamics and pinning effects in superconducting films with artificial magnetic structures. The fabrication of hybrid superconducting/ magnetic systems is presented together with the wide variety of properties that arise from the interaction between the superconducting vortex lattice and the artificial magnetic nanostructures....

We use quaternion molecular dynamics simulations to describe field-induced structural transitions in systems of few magnetic dipoles and their use for targeted medication delivery. Compact ring isomers of magnetic particles are contained, together with molecules of an active medication, inside inert microcapsules. The filled microcapsules may be transported within the body using a weak, inhomog...

The miniaturization of magnetic structures plays an important role for fundamental research as well as for technical applications. New experimental techniques allow for a preparation and investigation of magnetic systems of smaller and smaller spatial extension. This leads to an incremental interest in the understanding of the behavior of small magnetic particles and structures down to the nano...

Since the prediction by Dietl et al. in the year 2000, extensive research activities have been focused on the ZnObased diluted magnetic materials (DMSs). Earlier works were mainly performed using bulk or thin film materials with transition-metal doping, and diverse magnetic properties including ferromagnetism, paramagnetism, and diamagnetism have been reported. Identifying the dominant mechanis...
