Spiral magnetic phase in Li-doped Na2IrO3

The doping of the honeycomb lattice compound Na2IrO3 with cations having smaller ionic radius such as lithium was supposed to drive the system into a Kitaev spin liquid phase. Even at the smallest doping level the long range magnetic order, present in the ...

Heterometallic Fe-2(II)-U-V and Ni-2(II)-U-V Exchange-Coupled Single-Molecule Magnets: Effect of the 3d Ion on the Magnetic Properties

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

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 ...

Filming the formation and fluctuation of skyrmion domains by cryo-Lorentz transmission electron microscopy

Henrik Moodysson Rønnow, Arnaud Magrez, Marco Cantoni, Fabrizio Carbone, Jonathan White, Edoardo Baldini, Giulia Fulvia Mancini, Tatiana Latychevskaia, Ping Huang, Thierry Giamarchi, Yoshie Murooka

Magnetic skyrmions are promising candidates as information carriers in logic or storage devices thanks to their robustness, guaranteed by the topological protection, and their nanometric size. Currently, little is known about the influence of parameters su ...

Critical scattering of synchrotron radiation in lead zirconate-titanate with low titanium concentrations

Alexander Tagantsev

Diffuse scattering in the lead zirconate-titanate single crystal with a titanium concentration of 0.7 at % has been studied by the synchrotron radiation scattering method. Measurements have been performed both in the vicinity of the Brillouin zone center a ...

Magnetization reversal of an individual exchange-biased permalloy nanotube

Anna Fontcuberta i Morral, Dirk Grundler, Federico Matteini

We investigate the magnetization reversal mechanism in an individual permalloy (Py) nanotube (NT) using a hybrid magnetometer consisting of a nanometer-scale SQUID (nanoSQUID) and a cantilever torque sensor. The Py NT is affixed to the tip of a Si cantilev ...

A fast and reproducible method to quantify magnetic nanoparticle biodistribution

Heinrich Hofmann, Lionel André Maurizi, Usawadee Sakulkhu

The quantification of nanoparticles, particularly superparamagnetic iron oxide nanoparticles (SPIONs), both in vitro and in vivo has become highly important in recent years. Some methods, such as induced coupled plasma (ICP) spectroscopy and UV-visible che ...

Magnetization reversal mechanism of ramified and compact Co islands on Pt(111)

Harald Brune, Stefano Rusponi, Donat Fabian Natterer, Anne Lehnert, Alberto Cavallin, Géraud Moulas

We report on the magnetization reversal mechanism of Co islands on Pt(111) as a function of their size and shape. We measure the zero-field susceptibility chi(T) and low-temperature magnetization curves M(H) with in situ magneto-optical Kerr effect. Togeth ...

Interlayer exchange coupling in ordered Fe nanocluster arrays grown on Al2O3/Ni3Al(111)

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser, Fabio Donati, Luca Gragnaniello, Quentin Dubout, Sergio Vlaic, Alberto Cavallin

We have combined magneto-optical Kerr effect, scanning tunneling microscopy, and x-ray magnetic circular dichroism to study the magnetic properties and the morphology of Fe nanoparticles grown on 2 ML thick Al2O3/Ni3Al(111)-(root 67 x root 67)R12.2 degrees ...
