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 ...
EPFL2024Molecular intercalation in the van der Waals antiferromagnets FePS3 and NiPS3
Bruce Normand, Ying Chen, Sheng Xu, Shuo Li, Xiaoyu Xu, Zeyu Wang, Weiqiang Yu
We have performed electrochemical treatment of the van der Waals antiferromagnetic materials FePS3 and NiPS3 with the ionic liquid EMIM-BF4, achieving significant molecular intercalation. Mass analysis of the intercalated compounds, EMIMx-FePS3 and EMIMx-N ...
Amer Physical Soc2024Large impact of phonon lineshapes on the superconductivity of solid hydrogen
Phonon anharmonicity plays a crucial role in determining the stability and vibrational properties of high-pressure hydrides. Furthermore, strong anharmonicity can render phonon quasiparticle picture obsolete questioning standard approaches for modeling sup ...
Nature Portfolio2024Vapor compression and energy dissipation in a collapsing laser-induced bubble
Mohamed Farhat, Danail Obreschkow, Davide Bernardo Preso, Armand Baptiste Sieber
The composition of the gaseous phase of cavitation bubbles and its role on the collapse remains to date poorly understood. In this work, experiments of single cavitation bubbles in aqueous ammonia serve as a novel approach to investigate the effect of the ...
Melville2024Validation and Application of Hysteresis Loss Model for HTS Stacks and Conductors for Fusion Applications
Numerous conductor designs for pulsed magnets based on High Temperature Superconductors (HTS), featuring stacks of tapes are currently being proposed. A major contribution to the AC losses is expected to be given by hysteresis losses. Several numerical mod ...
Ieee-Inst Electrical Electronics Engineers Inc2024The magnet feeders for the European DEMO fusion reactor: Conceptual design and recent advances
Rainer Wesche, Roberto Guarino, Frédéric Michel
The magnet feeders are part of the critical systems of a fusion reactor since they represent the interface between the in-cryostat components at 4.5 K and the room-temperature cryogenic plant and power supply. The European DEMO tokamak foresees 16 toroidal ...
Lausanne2024Permanently magnetized elastomer rotating actuator using traveling waves
We report a soft actuator that generates continuous rotation of an object placed on it by electromagnetically exciting circular travelling waves in a soft disk. The disk, that serves as the stator, is made of a stretchable composite consisting of segments ...
Iop Publishing Ltd2024Educational Soft Underwater Robot with an Electromagnetic Actuation
As demonstrated by the Soft Robotics Toolkit Platform, compliant robotics pose an exciting educational opportunity. Underwater robotics using soft undulating fins is an expansive research topic with applications such as exploration of underwater life or re ...
New Rochelle2024Field-controlled multicritical behavior and emergent universality in fully frustrated quantum magnets
Phase transitions in condensed matter are a source of exotic emergent properties. We study the fully frustrated bilayer Heisenberg antiferromagnet to demonstrate that an applied magnetic field creates a previously unknown emergent criticality. The quantum ...
Berlin2024Magnetic structure and magnetoelectric properties of the spin-flop phase in LiFePO4
Ellen Fogh, Paola Caterina Forino, Sofie Janas
We investigate the magnetic structure and magnetoelectric(ME) effect in the high -field phase of the antiferromagnet LiFePO 4 above the critical field of 31 T. A neutron diffraction study in pulsed magnetic fields reveals the propagation vector to be q = 0 ...
