Spin 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 ...
EPFL2023Numerical 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 ...
ELSEVIER2023Increasing Magnetic Anisotropy in Bimetallic Nanoislands Grown on fcc(111) Metal Surfaces
Harald Brune, Stefano Rusponi, Sergio Vlaic, Dimitrios Mousadakos
The magnetic properties and the atomic scale morphology of bimetallic two-dimensional nanoislands, epitaxially grown on fcc(111) metal surfaces, have been studied by means of Magneto-Optical Kerr Effect and Scanning Tunneling Microscopy. We investigate the ...
MDPI2022Challenges and Applications to Operando and In Situ TEM Imaging and Spectroscopic Capabilities in a Cryogenic Temperature Range
Vasiliki Tileli, Martial Duchamp, Reinis Ignatans
In this Account, we describe the challenges and promising applications of transmission electron microscopy (TEM) imaging and spectroscopy at cryogenic temperatures. Our work focuses on two areas of application: the delay of electron-beam-induced degradatio ...
AMER CHEMICAL SOC2021Field-dependent roughness of moving domain walls in a Pt/Co/Pt magnetic thin film
The creep motion of domain walls driven by external fields in magnetic thin films is described by universal features related to the underlying depinning transition. One key parameter in this description is the roughness exponent characterizing the growth o ...
2021Low-temperature monoclinic layer stacking in atomically thin CrI3 crystals
Chromium triiodide, CrI3, is emerging as a promising magnetic two-dimensional semiconductor where spins are ferromagnetically aligned within a single layer. Potential applications in spintronics arise from an antiferromagnetic ordering between adjacent lay ...
2020Structural Disorder and Magnetic Order in Atomically Thin Crystals
This Thesis is mainly devoted to the exploration of the structural disorder and magnetic order in two-dimensional crystals by means of first-principles methodologies.
Firstly, we present a comparative study of defect formation in the semiconducting 2H and ...
EPFL2020Study and Characterization of Magnetic Materials for Beam Intensity Monitors at CERN
The number of particles in the beams used at CERN is measured by a family of devices called the Beam Current Transformers (BCTs). One of such devices is the DC Current Transformer (DCCT) measuring the total number of particles in an accelerator. The DCCT i ...
EPFL2018Genuinely Ferroelectric Sub-1-Volt-Switchable Nanodomains in HfxZr(1-x)O2 Ultrathin Capacitors
Mihai Adrian Ionescu, Igor Stolichnov, Enrico Colla, Matteo Cavalieri
The new class of fully silicon-compatible hafnia-based ferroelectrics with high switchable polarization and good endurance and thickness scalability shows a strong promise for new generations of logic and memory devices. Among other factors, their competit ...
2018Magnetic properties of surface-adsorbed single rare earth atoms, molecules, and atomic scale clusters
This thesis presents combined experimental and theoretical investigations of nanoscale, surface-supported magnets based on rare earths (RE) to understand and control the magnetic properties down to the scale of single atoms. We present the effects of adato ...
