Superconducting microwave oscillators as detectors for ESR spectroscopy

Nicola Brusadin, Jürgen Brugger, Giovanni Boero, Yu Rao, Reza Farsi, Hernán Furci, Roberto Russo, André Chatel

Microwave superconducting resonators are extensively studied in fields such as quantum computing and electron spin resonance (ESR) spectroscopy. However, the integration of superconducting resonators with feedback mechanisms to create ultra-low noise oscil ...

3D Characterisation of Turbulent Plasma Filaments Using Gas Puff Imaging in the Tokamak à Configuration Variable

Nicola Offeddu

A key challenge for the development of fusion reactors based on magnetic confinement, such as tokamaks and stellarators, is the control of the turbulent processes. The most prominent feature of turbulence in the Scrape-Off Layer (SOL), the volume between t ...

Heat and charge transport in H2O at ice-giant conditions from ab initio molecular dynamics simulations

Federico Grasselli

The impact of the inner structure and thermal history of planets on their observable features, such as luminosity or magnetic field, crucially depends on the poorly known heat and charge transport properties of their internal layers. The thermal and electr ...

Spin-Dependent Thermoelectric Transport in Cobalt-Based Heusler Alloys

Haiming Yu, Simon Granville, Junfeng Hu

Sitting at the intersection of spintronics and thermoelectricity, research investigating the coupling of thermoelectric, magnetic, and electrical transport properties in materials has recently found that the ferromagnetic Heusler alloys are the ideal testb ...

Multiple-Station Measurements of a Return-Stroke Electric Field From Rocket-Triggered Lightning at Distances of 68-126 km

Antonio Sunjerga, Quanxin Li

Far-field measurements of lightning-produced electromagnetic fields are of high importance for lightning location systems. Data from recorded lightning strokes can be, for example, used to assess the risk of lightning-induced damage in some geographical ar ...

Theories of topologically-induced phenomena in skyrmion-hosting magnetoelectric insulators

Oleksandr Kriuchkov

There once was a harsh competition between different computer memory technologies, and now we cheer triumph for the Random Access-Memory (RAM) devices, -- cheap, fast, tiny, stable. The competing Magnetic Bubble Memory had faded away as magnetic bubbles ar ...

Angular-dependent magnetization dynamics of kagome artificial spin ice incorporating topological defects

Dirk Grundler, Vinayak Shantaram Bhat

We report angular-dependent spin-wave spectroscopy on kagome artificial spin ice made of large arrays of interconnected Ni80Fe20 nanobars. Spectra taken in saturated and disordered states exhibit a series of resonances with characteristic in-plane angular ...

Leakage Flux Modelling in Magnetic Fluids Test Bench

Yves Perriard, Yoan René Cyrille Civet

The proposed paper discusses a new methodology to monitor the B-H curve of magnetic fluids, which have low relative permeability. The set-up consists of a magnetic circuit which encloses a sample. A first coil allows creating a magnetic field into the samp ...

Evolution of two-dimensional antiferromagnetism with temperature and magnetic field in multiferroic Ba2CoGe2O7

Bálint Náfrádi

We report on spherical neutron polarimetry and unpolarized neutron diffraction in zero magnetic field as well as flipping ratio and static magnetization measurements in high magnetic fields on the multiferroic square lattice antiferromagnet Ba2CoGe2O7. We ...

Investigation of field and diffusion time dependence of the diffusion-weighted signal at ultrahigh magnetic fields

Rolf Gruetter, Yohan Van de Looij, Nicolas Kunz

Over the last decade, there has been a significant increase in the number of high-magnetic-field MRI magnets. However, the exact effect of a high magnetic field strength (B0 ) on diffusion-weighted MR signals is not yet fully understood. The goal of this s ...

An Efficient Method Based on the Electromagnetic Time Reversal to Locate Faults in Power Networks

Mario Paolone, Farhad Rachidi-Haeri, Carlos Alberto Romero Romero, Gaspard Lugrin, Reza Razzaghi

This paper presents a new method based on the electromagnetic time-reversal (EMTR) theory for locating faults in power networks. The applicability of the EMTR technique to locate faults is first discussed. Using the classical transmission-line equations in ...

Supersolid phase induced by correlated hopping in spin-1/2 frustrated quantum magnets

Frédéric Mila, Julien Dorier

We show that correlated hopping of triplets, which is often the dominant source of kinetic energy in dimer-based frustrated quantum magnets, produces a remarkably strong tendency to form supersolid phases in a magnetic field. These phases are characterized ...

Lightning strikes to elevated structures: influence grounding conditions on currents and electromagnetic fields

Farhad Rachidi-Haeri, Marcos Rubinstein, Davide Pavanello, Emanuel Petrache

This paper presents an analysis of lightning return strokes to tall structures. The interaction of lightning with a tall structure is modeled using the antenna theory. The finite ground conductivity as well as the buried grounding system of the tall struct ...
