Low-temperature spin dynamics of a valence bond glass in Ba2YMoO6

We carried out ac magnetic susceptibility measurements and muon spin relaxation spectroscopy on the cubic double perovskite Ba2YMoO6, down to 50 mK. Below similar to 1 K the muon relaxation is typical of a magnetic insulator with a spin-liquid type ground ...

Charged Bis-Cyclometalated Iridium(III) Complexes with Carbene-Based Ancillary Ligands

Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Julien Edouard Frey

Charged cydometalated (CN) iridium(III) complexes with carbene-based ancillary ligands are a promising family of deep-blue phosphorescent compounds. Their emission properties are controlled primarily by the main CN ligands, in contrast to the classic ...

Low-temperature spin dynamics of a valence bond glass in Ba

Henrik Moodysson Rønnow, Julian Piatek

We carried out ac magnetic susceptibility measurements and muon spin relaxation spectroscopy on the cubic double perovskite Ba2YMoO 6, down to 50 mK. Below ∼1 K the muon relaxation is typical of a magnetic insulator with a spin-liquid type ground state, i. ...

Combined large spin splitting and one-dimensional confinement in surface alloys

Klaus Kern, Marco Grioni, Alberto Crepaldi

We have found and characterized, by angle-resolved photoelectron spectroscopy (ARPES), quasi-one-dimensional spin-split states in chain-like surface alloys formed by large Z elements (Bi and Pb) at the Cu(110) surface. The ARPES results are supported by fi ...

Role of π-Acceptor Effects in Controlling the Lability of Novel Monofunctional Pt(II) and Pd(II) Complexes: Crystal Structure of [Pt(tripyridinedimethane)Cl]Cl

The kinetics and mechanism of substitution reactions of novel monofunctional Pt(tpdm)Cl and Pd(tpdm)Cl complexes (where tpdm = tripyridinedimethane) and their aqua analogues with thiourea (tu), L-methionine (L-met), glutathione (GSH), and guanosi ...

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 ...

Localized and delocalized Ti 3d carriers in LaAlO3/SrTiO3 superlattices revealed by resonant inelastic x-ray scattering

Thorsten Schmitt, Joël Mesot

The important source of interface conductivity in LaAlO3/SrTiO3 heterostructures, the Ti 3d carriers, is probed with resonant inelastic x-ray scattering at the Ti 2p(3/2) edge of epitaxially grown superlattices. We reveal unambiguously the generation of bo ...

Tuning the spin texture in binary and ternary surface alloys on Ag(111)

Klaus Kern, Jan Hugo Dil, Isabella Gierz

A giant spin splitting has been observed in surface alloys on noble metal (111) surfaces as a result of a strong structural modification at the surface as well as the large atomic spin-orbit interaction (SOI) of the alloy atoms. These surface alloys are an ...

Magnetic Decoupling of Surface Fe3+ in Magnetite Nanoparticles upon Nitrocatechol-Anchored Dispersant Binding

Esther Amstad

Bind and distort: NitroDOPA, an anchor shown to irreversibly couple dispersants and functional groups to superparamagnetic Fe 3O 4 nanoparticles, can magnetically decouple Fe 3+ in a nanoparticle surface layer. The strong binding of nitroDOPA distorts the ...

On the enzymatic activity of catalase: an iron L-edge X-ray absorption study of the active centre

Majed Chergui

Catalase and methaemoglobin have very similar haem groups, which are both ferric, yet catalase decomposes hydrogen peroxide to water and oxygen very efficiently, while methaemoglobin does not. Structural studies have attributed this behaviour to their diff ...
