Origin of Perpendicular Magnetic Anisotropy and Large Orbital Moment in Fe Atoms on MgO

Harald Brune, Stefano Rusponi, Marina Pivetta, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Luca Gragnaniello, Giulia Elisabetta Pacchioni

We report on the magnetic properties of individual Fe atoms deposited on MgO(100) thin films probed by x-ray magnetic circular dichroism and scanning tunneling spectroscopy. We show that the Fe atoms have strong perpendicular magnetic anisotropy with a zer ...

Topologically robust sound propagation in an angular-momentum-biased graphene-like resonator lattice

Romain Christophe Rémy Fleury

Topological insulators do not allow conduction in the bulk, yet they support edge modes that travel along the boundary only in one direction, determined by the carried electron spin, with inherent robustness to defects and disorder. Topological insulators ...

Design of Single-Molecule Magnets: Insufficiency of the Anisotropy Barrier as the Sole Criterion

Jan Gui-Hyon Dreiser, Romain Sibille

Determination of the electronic energy spectrum of a trigonalsymtnetry mononuclear Yb3+ single-molecule magnet (SMM) by highresolution absorption and luniinescente spectroscopies reveals that the first excited electronic doublet is placed nearly 500 cm(-1) ...

Comparing XMCD and DFT with STM spin excitation spectroscopy for Fe and Co adatoms on

Harald Brune, Stefano Rusponi, Pietro Gambardella, Markus Etzkorn, Anne Lehnert

We report on the magnetic properties of Fe and Co adatoms on a Cu2N/Cu(100)-c(2 x 2) surface investigated by x-ray magnetic dichroism measurements and density functional theory (DFT) calculations including the local coulomb interaction. We compare these re ...

Hyperpolarized para-Ethanol

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Basile Vuichoud, Daniele Mammoli

We show that an imbalance between the populations of singlet (S) and triplet (T) states in pairs of magnetically equivalent spins can be generated by dissolution dynamic nudear polarization: In partly deuterated ethanol ((CD3CH2OD)-C-13), this T/S imbalanc ...

Effect of Heat Current on Magnetization Dynamics in Magnetic Insulators and Nanostructures

Francesco Antonio Vetrò

The term "spin caloritronics" defines a novel branch of spintronics that focuses on the interplay between electron spins with heat currents. In the frame of this research area, this thesis is aimed at investigating the effect of a heat current on magnetiza ...

Restoring the Co Magnetic Moments at Interfacial Co-Porphyrin Arrays by Site-Selective Uptake of Iron

Harald Brune, Stefano Rusponi, Markus Etzkorn, Uta Schlickum, Sebastian Stepanow, Torsten Houwaart

Magnetochemistry recently emerged as a promising approach to control addressable spin arrays on surfaces. Here we report on the binding, spatial ordering, and magnetic properties of Fe on a highly regular Co-tetraphenylporphyrin (Co-TPP) template and highl ...

Magnetic model in multiferroic NdFe3(BO3)(4) investigated by inelastic neutron scattering

Henrik Moodysson Rønnow

We performed inelastic neutron scattering measurements on single crystals of NdFe3((BO3)-B-11)(4) to explore the magnetic excitations, to establish the underlying Hamiltonian, and to reveal the detailed nature of hybridization between the 4f and 3d magneti ...

Linear spin wave theory for single-Q incommensurate magnetic structures

Sándor Tóth

Linear spin wave theory provides the leading term in the calculation of the excitation spectra of long-range ordered magnetic systems as a function of 1/root S. This term is acquired using the Holstein-Primakoff approximation of the spin operator and valid ...

Poleable Nanoparticles as Fillers Towards Non-linear Optically Active Actuators

Yee Song Ko

A new type of poleable dielectric elastomer is introduced herein. The elastomer contains polymer nanoparticles with frozen molecular dipoles, which can be oriented at elevated temperatures in an electric field via poling. The aim is to provide a soft mater ...
