Magnetism of Single Surface Adsorbed Atoms Studied with Radio-Frequency STM
This thesis investigates the magnetic properties of single atoms and molecules adsorbed on thin magnesium oxide decoupling layers, grown on a silver single crystal. To address these systems experimentally, we use a low temperature scanning tunneling micros ...
EPFL2024Magnon-Assisted Magnetization Reversal of Ni81Fe19 Nanostripes on Y3Fe5O12 with Different Interfaces
Dirk Grundler, Andrea Mucchietto, Korbinian Baumgärtl
Magnetic bit writing by short-wave magnons without conversion to the electrical domain is expected to be a game-changer for in-memory computing architectures. Recently, the reversal of nanomagnets by propagating magnons was demonstrated. However, experimen ...
2024Spin Textures in 2D Magnets
The continuous reduction of the structural size in nanotechnology slowed down over the last decade, approaching the natural limit of single atoms as building blocks of matter. Therefore, intensive research is directed toward exploring new frontiers, in par ...
EPFL2023Ultrafast control of emergent quantum matter probed by electron microscopy
Benoît Guilhem Michel Binh Truc
In the quest for controlling materials' properties, light as an external stimulus has a special place as it can create new states of matter and enable their ultrafast manipulation. In particular, spintronics, an exciting emergent field relying on the elect ...
EPFL2023Quantum engineering and detection of advanced radiation beams
Controlling and shaping radiation beams is fundamental for a better understanding of radiation-matter interaction and advancing experimental techniques for material characterization at high spatial resolution.In particular, the current trend in the miniatu ...
EPFL2023Snap buckling of bistable beams under combined mechanical and magnetic loading
Pedro Miguel Nunes Pereira de Almeida Reis, Dong Yan, Tomohiko Sano, Arefeh Abbasi
We investigate the mechanics of bistable, hard-magnetic, elastic beams, combining experiments, finite-element modelling (FEM) and a reduced-order theory. The beam is made of a hard magneto-rheological elastomer, comprising two segments with antiparallel ma ...
ROYAL SOC2023Numerical study of fully baffled Super-XL-mode discharges on TCV
Christian Gabriel Theiler, Davide Galassi
We present a numerical study of three fully baffled L-mode TCV discharges with three different values of the outer strike-point major radius/total flux expansion, showing that the beneficial effect of large strike point radius is partially screened in thes ...
ELSEVIER2023Ferroelectric Effects Probed by in situ Transmission Electron Microscopy
Ferroelectric perovskite oxides are widely used in sensors, actuators and optical modulators and, at the same time, they show promise for implementation in future applications such as energy storage, memory and cooling devices. At the infancy of the discov ...
EPFL2022Magnetic structure of the topological semimetal Co3Sn2S2
Henrik Moodysson Rønnow, Ivica Zivkovic, Jian Rui Soh
Co3Sn2S2 has recently been predicted to be a Weyl semimetal in which magnetic order is key to its behavior as a topological material. Here, we report unpolarized neutron diffraction and spherical neutron polarimetry measurements, supported by magnetization ...
AMER PHYSICAL SOC2022Decoding the Mechanisms of Phase Transitions from In Situ Microscopy Observations
Vasiliki Tileli, Reinis Ignatans
Analysis of the temperature- and stimulus-dependent imaging data toward elucidation of the physical transformations is an ubiquitous problem in multiple fields. Here, temperature-induced phase transition in BaTiO3 is explored using the machine learning ana ...
