Layer resolved structural relaxation at the surface of magnetic FePt icosahedral nanoparticles.

TL;DR: The periodic shell structure and surface reconstruction of metallic FePt nanoparticles with icosahedral structure has been quantitatively studied by high-resolution transmission electron microscopy with focal series reconstruction with sub-angstrom resolution and finds the lattice spacing of (111) planes in the surface region to be size dependent.
Journal ArticleDOI

Quantitative determination of effective dipole and monopole moments of magnetic force microscopy tips

TL;DR: In this paper, the authors presented experimental results on the characterization of commercially available magnetic force microscopy (MFM) thin film tips as a function of an external magnetic field, and gave a quantitative relationship on how absolute values of the magnetic dipole and monopole moments and their location within the tip depend on a characteristic decay length of the z component of the Magnetic Field being detected.
Journal ArticleDOI

Tailored nanoparticle films from monosized tin oxide nanocrystals: Particle synthesis, film formation, and size-dependent gas-sensing properties

TL;DR: In this article, a thin film synthesis technique was developed to investigate the change of gas-sensitive properties of undoped tin oxide nanoparticle films depending on particle size, and the effect of in-flight oxidation, sintering, and crystallization on the structure, size and size distribution of nanoparticles have been studied in detail.
Journal ArticleDOI

Magnetoresistance of single Co nanowires

TL;DR: In this paper, the magnetic field H c (coercive fields) was determined as a function of the angle α between current and field direction (from in plane to out of plane) and of the width w of the Co nanowires.
Journal ArticleDOI

Electromigration in self-organized single-crystalline silver nanowires

TL;DR: In this paper, single-crystalline silver nanowires were grown on 4° vicinal silicon (100) substrates by self-organization and were contacted by electron beam lithography.
