Phase transitions in magnetic clusters and other finite systems
… seven articles dealing with phase transitions of magnetic clusters or other finite systems. We show that phase transitions in finite systems, which can be experimentally seen only in floppy humps of the specific heat or the magnetic susceptibility, can be quantitatively described by an analysis of …

57Fe Mössbauer spectroscopic study of the spin-glass transitions in the mixed spinel series Mg0.9+xFe2(1-x)Ni0.1Ti0.1O4
Magnetically diluted materials with spinel structure can fulfil the conditions for spin-glass behaviour. On the other hand, such spinels were also reported to exhibit a superparamagnetic behaviour due to the existence of small magnetic clusters in the spinel lattice. In order to gain some insight …

Dynamics of Micro-Particles in Complex Environment
… Janus catalytic micromotors (JCMs) and magnetic clusters, in complex environment are studied using numerical simulations. The self-diffusiophoresis of JCMs in a confined environment is studied first. Overall, the translocation of a JCM through a short pore is slowed down by pore walls, …

Granular Alloy Film Synthesis Using Ionized Cluster Beam Deposition
… ion beam optics, and the production of nanoclusters and their magnetic behavior. Films are grown by simultaneous deposition of ionized nanoclusters from a beam and of atoms from an evaporation source. The resultant films are of granular structure; that is, they have clusters of nanometer …

Synthesis and Characterization of Novel Polyethers and Polypeptides for Use in Biomedicine and Magnetic Resonance Imaging
… amide bonds. In this research, we have prepared magnetic block ionomer complexes based on poly(ethylene oxide)-b-poly(L-glutamic acid) copolymers. This is of interest due to the biocompatibility and biodegradable nature of the poly(L-glutamic acid) component of the backbone. Allyl- and …

Controlled emulsion droplet solvent evaporation for particle production
… is extremely versatile, to create, for example, magnetic nanoparticles, polymeric Janus beads, and crystalline particles. The emulsion droplets act as confined spaces, or templates, within which the particles can form. Upon removal of the solvent, primary magnetite nanoparticles pack into dense …

Self-assembly of anisotropic nanostructures and interferometric spectroscopy
… a simple method for assembling superparamagnetic nanoparticles (SPIONs) into structure-controlled 1D chains in a rotating magnetic field. The length of the SPION chains can be well described by an exponential distribution, as is also seen in SPION chains in a static field. In addition, …

Tunable High-Field/ High-Frequency ESR and High-Field Magnetization on Single-Molecule Clusters
In this work, low dimensional iron group clusters have been studied by application of high magnetic fields. The magnetization has been probed with an MPMS as function of temperature and field. The combination with pulse field measurements up to 52\,T allowed determination of the magnetic exchange …
