Tunable Short-Wavelength Spin-Wave Emission and Confinement in Anisotropy-Modulated Multiferroic Heterostructures

We report on the generation and confinement of short-wavelength spin waves in a continuous film with periodically modulated magnetic anisotropy. The concept, which is demonstrated for strain-coupled Co40Fe40B20/BaTiO3 heterostructures, relies on abrupt rot ...

Rare Earth and Bimetallic Transition Metal Islands at Surfaces

Dimitrios Mousadakos

This thesis reports on the growth and on the magnetic characterization of nanostructures made of 3d-4d transition metals and rare earths. In all the experiments the nanostructures have been grown by atomic beam epitaxy (ABE) in ultra high vacuum conditions ...

Collapse phenomena of deformed cavitation bubbles

Outi Supponen

Cavitation bubbles are a topic of long-standing interest owing to the powerful phenomena associated with their collapse. Their unique ability to focus energy typically causes damage in hydraulic machinery (turbines, pumps, propellers, ...) but, if managed ...

Magnetization reversal in individual Py and CoFeB nanotubes locally probed via anisotropic magnetoresistance and anomalous Nernst effect

Anna Fontcuberta i Morral, Dirk Grundler

Using anisotropic magnetoresistance in a multi-probe configuration and local heating with a scanning laser, we investigate the magnetization reversal of individual permalloy (Py) and CoFeB nanotubes with spatial resolution. Nanocrystalline Py and amorphous ...

Skyrmion dynamics under uniaxial anisotropy

Dirk Grundler

Broadband microwave spectroscopy has been performed on single-crystalline GaV4S8, which exhibits a complex magnetic phase diagram including cycloidal and Neel-type skyrmion lattice phases below 13 K. At small magnetic fields two collective modes with large ...

Neel-like domain walls in ferroelectric Pb(Zr,Ti)O-3 single crystals

Nava Setter, Tomas Sluka, Xiankui Wei

In contrast to the flexible rotation of magnetization direction in ferromagnets, the spontaneous polarization in ferroelectric materials is highly confined along the symmetry-allowed directions. Accordingly, chirality at ferroelectric domain walls was trea ...

Magnetic anisotropy in the frustrated spin-chain compound beta-TeVO4

Helmuth Berger

Isotropic and anisotropic magnetic behavior of the frustrated spin-chain compound beta-TeVO4 is reported. Three magnetic transitions observed in zero magnetic field are tracked in fields applied along different crystallographic directions using magnetizati ...

Out-of-Plane Alignment of Er(trensal) Easy Magnetization Axes Using Graphene

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

We have studied Er(trensal) single -ion magnets adsorbed on graphene/Ru(0001), on graphene/Ir(111), and on bare Ru(0001) by scanning tunneling microscopy and X-ray absorption spectroscopy. On graphene, the molecules self -assemble into dense and well -orde ...

Semiclassical theory of the magnetization process of the triangular lattice Heisenberg model

Frédéric Mila, Tommaso Coletta, Karlo Penc, Tamás András Tóth

Motivated by the numerous examples of 1/3 magnetization plateaux in the triangular-lattice Heisenberg antiferromagnet with spins ranging from 1/2 to 5/2, we revisit the semiclassical calculation of the magnetization curve of that model, with the aim of com ...
