Uranium and manganese assembled in a wheel-shaped nanoscale single-molecule magnet with high spin-reversal barrier

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

Discrete molecular compounds that exhibit both magnetization hysteresis and slow magnetic relaxation below a characteristic 'blocking' temperature are known as single-molecule magnets. These are promising for applications including memory devices and quant ...

The Quantum Magnetism of Individual Manganese-12-Acetate Molecular Magnets Anchored at Surfaces

Klaus Kern, Markus Ternes, Stephan Rauschenbach, Gordon Rinke, Nicha Thontasen

The high intrinsic spin and long spin relaxation time of manganese-12-acetate (Mn-12) makes it an archetypical single molecular magnet. While these characteristics have been measured on bulk samples, questions remain whether the magnetic properties replica ...

X-ray Magnetic Circular Dichroism (XMCD) Study of a Methoxide-Bridged Dy^III-Cr^III Cluster Obtained by Fluoride Abstraction from cis-[Cr^III F_2 (phen)_2]^+

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser

An isostructural series of dinuclear chromium(III)-lanthanide(III) clusters is formed by fluoride abstraction of cis-CrF2(phen)(2) by Ln(3+) resulting in LnF(3) and methoxide-bridged Cr-Ln clusters (Ln = Nd (1), Tb (2), Dy (3)) of formula [Cr-III(phen ...

EDIPO quench detection system: concept and development

Pierluigi Bruzzone, Stephen Alfred March, Giancarlo Croari, Roland Felder

EDIPO is the new 12.5 T superconducting test facility that is being installed at CRPP in Villigen, Switzerland. It will be placed beside the existing test facility SULTAN. The main purpose of both facilities is testing samples for the ITER project. EDIPO w ...

Site-selective quantum correlations revealed by magnetic anisotropy in the tetramer system SeCuO_{3}

László Forró, Henrik Moodysson Rønnow, Ivica Zivkovic, Helmuth Berger, Philip Pattison, Krunoslav Prsa, Zlatko Mickovic

We present the investigation of a monoclinic compound SeCuO3 using x-ray powder diffraction, magnetization, torque, and electron-spin-resonance. Structurally based analysis suggests that SeCuO3 can be considered as a three-dimensional network of tetramers. ...

Atomic-scale engineering of magnetic anisotropy of nanostructures through interfaces and interlines

Harald Brune, Stefano Rusponi, Philipp Buluschek, Sergio Vlaic, Géraud Moulas

The central goals of nanoscale magnetic materials science are the self-assembly of the smallest structure exhibiting ferromagnetic hysteresis at room temperature, and the assembly of these structures into the highest density patterns. The focus has been on ...

Development of magnet technologies for HTS insert coils

Pierluigi Bruzzone, Davide Uglietti, Boris Stepanov, Rainer Wesche, Stephen Alfred March, Natalia Hanna Glowa

An existing Nb3Sn laboratory magnet generating a magnetic field of 12 T is intended to be upgraded to 16 T by means of the use of a high temperature superconductor (HTS) insert coil. An outline design of the HTS insert coil is presented. In the design, the ...

Direct observation of a ferri-to-ferromagnetic transition in a fluoride-bridged 3d–4f molecular cluster

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser

We report on the synthesis, crystal structure and magnetic characterisation of the trinuclear, fluoride-bridged, molecular nanomagnet [Dy(hfac)(3)(H2O)-CrF2(py)(4)-Dy(hfac)(3)(NO3)] (1) (hfacH = 1,1,1,5,5,5-hexafluoroacetylacetone, py = pyridine) and a clo ...

Spin-wave excitations and superconducting resonant mode in CsxFe2−ySe2

Jonathan White, Peter Babkevich, Kazimierz Conder

We report neutron inelastic scattering measurements on the normal and superconducting states of single-crystalline Cs0.8Fe1.9Se2. Consistent with previous measurements on RbxFe2−ySe2, we observe two distinct spin excitation signals: (i) spin-wave excitatio ...

Magnetic states of an individual Ni nanotube probed by anisotropic magnetoresistance

Anna Fontcuberta i Morral, Dirk Grundler, Daniel Rüffer, Martin Heiss, Eleonora Russo

Defined magnetization states in magnetic nanotubes could be the basic building blocks for future memory elements. To date, it has been extremely challenging to measure the magnetic states at the single-nanotube level. We investigate the magnetization state ...
