Electronic Structure of Surface-supported Bis(phthalocyaninato) terbium(III) Single Molecular Magnets

The electronic structure of isolated bis(phthalocyaninato) terbium(ill) molecules, a novel single-molecular-magnet (SMM), supported on the Cu(111) surface has been characterized by density functional theory and scanning tunneling spectroscopy. These studie ...

Interaction Effects in Dilute Cluster-Assembled Magnetic Nanostructures

Giulia Di Domenicantonio

We have prepared dilute nanostructured magnetic samples by co-deposition of preformed Cobalt clusters with a narrow size distribution around 40 atoms/cluster in Silver matrices. Magnetoresistance measurements are used to derive information about the magnet ...

Co-encapsulation of dexamethasone 21-acetate and SPIONs into biodegradable polymeric microparticles designed for intra-articular delivery

Heinrich Hofmann, Alke Fink, Olivier Jordan

Objective: Intra-articular drug delivery systems still suffer from too short-lasting effects. Magnetic particles retained in the joint using an external magnetic field might prolong the local release of an anti-inflammatory drug. For the purpose, superpara ...

Transient Heat Transfer Model and Stability Analysis of helium-cooled Superconducting Cables

Luca Bottura, Pier Paolo Granieri, Panagiota Xydi

The stability is a key issue to design superconducting magnets and to ensure their proper exploitation. This is the case of the imminent operation of the Large Hadron Collider (LHC) accelerator, which requires a good knowledge of the stability margin of it ...

Magnetic anisotropy of paramagnetic and ferromagnetically ordered state of single crystal BaVSe3

László Forró, Helmuth Berger, Ana Akrap

Anisotropic magnetism of single crystal BaVSe3 was Studied for the first time by the combination of the susceptibility and torque methods. As reported previously for polycrystalline sample, BaVSe3 undergoes ferromagnetic ordering below 43 K. Well above fer ...

Magnetic structure of the S=1Ni(5)(TeO3)(4)Br-2 layered system governed by magnetic anisotropy

Helmuth Berger

Magnetization, neutron diffraction, and antiferromagnetic resonance measurements were employed to investigate the magnetic ground state of Ni-5(TeO3)(4)Br-2 single crystal. Despite the layered topology of the Ni2+ sites, typical for frustrated antiferromag ...

BCCFe surface and cluster magnetism using a magnetic potential

Helena Van Swygenhoven

A semi-empirical potential for ferromagnetic bcc iron that also models the co-linear magnetic moment of each atom, has been applied to clusters and surfaces. Surface energies of low index facets, surface relaxation and magnetic moment are calculated and co ...

Structure and magnetism of atomically thin Fe layers on flat and vicinal Pt surfaces

Klaus Kern, Harald Brune, Stefano Rusponi, Pietro Gambardella, Violetta Sessi

Ultrathin Fe films on Pt substrates have been investigated under ultrahigh vacuum conditions by scanning tunneling microscopy, low energy electron diffraction, magneto-optical Kerr effect, x-ray magnetic circular dichroism measurements, and Kerr microscopy ...

Magnetism of Fe clusters and islands on Pt surfaces

Klaus Kern, Harald Brune, Stefano Rusponi

Clusters and islands of Fe atoms have been prepared by noble gas buffer layer assisted growth as well as by standard molecular beam epitaxy on Pt substrates. Xe buffer layers have been utilized to promote the formation of compact, relaxed Fe clusters with ...

Design and optimization of the 12.5 T EFDA dipole magnet

Pierluigi Bruzzone, Luca Bottura

The aim of this paper is to provide an overview of a recent study carried out-within the framework of the European Fusion Program-to design a 12.5 T superconducting dipole. By focusing on the CICC based design option, the overall design procedure is presen ...
