Estimation of performance of Nb3Sn CICC with thermal strain distribution
Pierluigi Bruzzone, Kamil Sedlák, Rainer Wesche
In the last few years, the critical temperature (Tc) of several ITER cable-in-conduit conductors (CICC) was determined by magnetization measurements at zero current. The distribution of the critical temperatures (Tc), caused by variation of strain in the N ...
2020High field magnetization of FePS3
Henrik Moodysson Rønnow, Diane Virginie Marie Lançon
High field magnetization measurements in pulsed fields up to 65 T have been performed on FePS3, which is nominally a good example of a two-dimensional Ising-like antiferromagnet on a honeycomb lattice. Measurements with the field parallel to the moment dir ...

Henrik Moodysson Rønnow, Arnaud Magrez, Marco Cantoni, Fabrizio Carbone, Ping Huang, Thomas Schönenberger
While in 3D materials melting is a single, first-order phase transition, in 2D systems, it can also proceed via an intermediate phase. For a skyrmion lattice in Cu2OSeO3, magnetic field variations can tune this quasiparticle 2D solid into a skyrmion liquid ...
NATURE PUBLISHING GROUP2020A radio ridge connecting two galaxy clusters in a filament of the cosmic web
Galaxy clusters are the most massive gravitationally bound structures in the Universe. They grow by accreting smaller structures in a merging process that produces shocks and turbulence in the intracluster gas. We observed a ridge of radio emission connect ...
AMER ASSOC ADVANCEMENT SCIENCE2019From Anomaly Detection to Rumour Detection using Data Streams of Social Platforms
Social platforms became a major source of rumours. While rumours can have severe real-world implications, their detection is notoriously hard: Content on social platforms is short and lacks semantics; it spreads quickly through a dynamically evolving netwo ...
ASSOC COMPUTING MACHINERY2019Reduced models for parallel magnetic field fluctuations and their impact on pressure gradient driven MHD instabilities in axisymmetric toroidal plasmas
Jonathan Graves, Samuel Lanthaler, Daniele Brunetti
It is well known that parallel magnetic field fluctuations are connected with finite plasma beta effects. It can therefore be expected that Reduced Models that simplify or neglect the parallel magnetic field may not capture the salient physics of all types ...
2019Persistent antiferromagnetic order in heavily overdoped Ca1-xLaxFeAs2
László Forró, Henrik Moodysson Rønnow, Ivica Zivkovic, Philip Johannes Walter Moll, Ana Akrap, Sergiy Katrych, Maja Deborah Bachmann, Edoardo Martino
In the Ca1-xLaxFeAs2 (1 1 2) family of pnictide superconductors, we have investigated a highly overdoped composition (x = 0.56), prepared by a high-pressure, high-temperature synthesis. Magnetic measurements show an antiferromagnetic transition at T-N = 12 ...
2019Light scattering from the critical modes of the Verwey transition in magnetite
Fabrizio Carbone, Simone Borroni
We present inelastic light scattering data on a single crystal of magnetite (Fe3O4) across the Verwey transition. We identify anomalies of the lattice vibrations that originate from strong coupling to electronic excitations. We reveal spectroscopic signatu ...
AMER PHYSICAL SOC2018Anomalous spin dynamics in the coupled spin tetramer system CuSeO3
We report high-field magnetization, high-frequency electron spin resonance (ESR), and Se-77 nuclear magnetic resonance (NMR) measurements on the linear spin tetramer system CuSeO3, consisting of strongly interacting Cu(1) dimers and weakly coupled Cu(2) sp ...
Amer Physical Soc2017Magnetic and thermodynamic properties of CuxTiSe2 single crystals
We present a detailed study of the phase diagram of copper-intercalated TiSe2 single crystals, combining local Hall-probe magnetometry, tunnel diode oscillator technique (TDO), and specific-heat and angle-resolved photoemission spectroscopy measurements. A ...
