MnO nanoparticles as the cause of ferromagnetism in bulk dilute Mn-doped ZnO

Henrik Moodysson Rønnow, Arnaud Magrez, Diane Virginie Marie Lançon, Goran Nilsen, Ping Huang

We show that the observed ferromagnetic behavior of ZnO lightly doped with Mn coincides with the presence of MnO nanoparticles, whereas cluster-free Mn doped ZnO behaves paramagnetically. This conclusion is reached by a study of the structural and magnetic ...

2016

This thesis encompasses an investigation of organic molecules on metallic substrates as well as a study of electronic and magnetic effects in atomic-sized palladium contacts. For this, a scanning tunneling microscope, operating at 6 K and ultra-high vacuum ...

Cyanide Single-Molecule Magnets Exhibiting Solvent Dependent Reversible "On" and "Off" Exchange Bias Behavior

Jan Gui-Hyon Dreiser

The syntheses, structures, and magnetic properties of four new complex salts, (PPN){Mn-III(salphen)(MeOH)[M-III(CN)(6)]} 7MeOH (Mn2M 7MeOH) (M = Fe, Ru, Os and Co; PPN+ = bis(triphenylphosphoranylidene)ammonium cation; H2salphen = N,N'-bis(salicyliden ...

American Chemical Society2015

Uranium-based compounds have been put forward as ideal candidates for the design of single-molecule magnets (SMMs) with improved properties, but to date, only two examples of exchange-coupled 3d-5f SMM containing uranium have been reported and both are bas ...

Wiley-Blackwell2015

The synthesis, structural characterization and magnetic properties of a 1D zig-zag coordination polymer based on a cation-cation [((UO2)-O-V)Mn-II] repeated unit are reported; it shows single chain magnet (SCM) behaviour with a high energy barrier of 122 K ...

Royal Society of Chemistry2015

The magnetic properties of the two uranium coordination compounds, [K(18c6)][U(OSi-((OBu)-Bu-t)(3))(4)] and [K(18c6)][U(N(SiMe3)(2))(4)], both presenting the U-III ion in similar pseudotetrahedral coordination environments but with different O- or N-donor ...

Amer Chemical Soc2014

High Cr (9-14% Cr) ferritic/martensitic steels are considered as one of the most promising candidates for structural materials for advanced nuclear power plants. Therefore, the understanding of the evolution of properties under operation conditions is of p ...

EPFL2013

A family of lanthanide complexes has been synthesized by the subcomponent self-assembly methodology. Molecular architectures, which were stable in solution and under ambient conditions, were designed by the in situ formation of ligands around lanthanide io ...

Strong coupling of Sm and Fe magnetism in SmFeAsO as revealed by magnetic x-ray scattering

Henrik Moodysson Rønnow, Xiao Wang

The magnetic structures adopted by the Fe and Sm sublattices in SmFeAsO have been investigated using element-specific x-ray resonant and nonresonant magnetic scattering techniques. Between 110 and 5 K, the Sm and Fe moments are aligned along the c and a di ...

Magnetic properties of the magnetoelectric compound Cu2OSeO3: Magnetization and Se-77 NMR study

Jean-Philippe Ansermet, Helmuth Berger, Simon Granville

We present magnetization and Se-77 Nuclear Magnetic Resonance (NMR) measurements in single crystals of the magnetoelectric compound Cu2OSeO3. The temperature and field dependence of the magnetization suggest a ferrimagnetic ordering at T-c similar or equal ...
