GHz spectroscopy on a rare-earth quantum magnet
In this report, spectroscopy was used to track the energy of different states in a LiHoF4 sample around its critical temperature. The experimental setup consist of a Cooper cavity with the sample, an antenna and a resonator inside. This cavity is attached ...
2022Small-angle neutron scattering study of mesoscale magnetic disordering and skyrmion phase suppression in the frustrated chiral magnet Co6.75Zn6.75Mn6.51
Henrik Moodysson Rønnow, Jonathan White
Co-Zn-Mn chiral cubic magnets display versatile magnetic skyrmion phases, including equilibrium phases stable far above and far below room temperature, and the facile creation of robust far-from-equilibrium skyrmion states. In this system, compositional di ...
INT UNION CRYSTALLOGRAPHY2022Estimation 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 ...
2020Spin Correlations and Short-Range Magnetic Order in the Honeycomb-Layered Na2Ni2TeO6
Irina Safiulina, Artem Korshunov
An experimental study of long-range magnetic order formation mechanisms in a layered structure with a honeycomb arrangement of the magnetic atoms Na2Ni2TeO6 is conducted. For the first time, the strong spin correlations are directly observed above the Neel ...
WILEY-V C H VERLAG GMBH2020Critical fluctuations in the spin-orbit Mott insulator Sr3Ir2O7
X-ray magnetic critical scattering measurements and specific heat measurements were performed on the perovskite iridate Sr3Ir2O7. We find that the magnetic interactions close to the Neel temperature T-N = 283.4(2) K are three-dimensional. This contrasts wi ...
2019Singlet state formation and its impact on the magnetic structure in the tetramer system SeCuO3
Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Helmuth Berger, Krunoslav Prsa, Peter Babkevich
We present an experimental investigation of the magnetic structure in a tetramer system SeCuO3 using neutron powder-diffraction and nuclear resonance techniques. We establish a commensurate antiferromagnetic ordering with a propagation vector k = (0, 0, 1) ...
2018Neutron spectroscopy in the layered quantum magnet SrCu₂(BO₃)₂ and in transition metal phosphorus trisulfides (MPS₃)
Collective magnetic excitations are a fascinating aspect of condensed matter physics, where neutron scattering can provide valuable insight into the magnetic properties of physical realisations of model systems. This thesis focuses on the excitation spectr ...
EPFL2017Building Composite Iron-Manganese Oxide Flowerlike Nanostructures: A Detailed Magnetic Study
Here we show that it is possible to produce different magnetic core multiple shell heterostructures from monodisperse Fe3O4 spherical magnetic seeds by finely controlling the amount of a manganese precursor and using, in a smart and simple way, a cation-ex ...
Amer Chemical Soc2017Anisotropic spin-flip-induced multiferroic behavior in kagome Cu3Bi(SeO3)(2)O2Cl
Compared to the previous report on Cu3Bi(SeO3)(2)O2X (X = Cl, Br) [V. Gnezdilov et al., (arXiv: 1604.04249)], where no dielectric anomaly was observed without magnetic field near T-N similar to 25.6K, we further present the dielectric behaviors without and ...
Amer Physical Soc2017Single crystals of superconducting SmFeAsOHx: Structure and properties
László Forró, Alla Arakcheeva, Richard Gaal, Janusz Andrzej Karpinski, Andrea Pisoni, Sergiy Katrych, Ping Huang, Péter Krisztián Matus
We report the synthesis, structure, and superconducting properties of single crystals of SmFeAsOHx. The crystals were grown at high pressure and high temperature using a cubic anvil technique. H-1-NMR studies confirm the presence of H atoms in the samples. ...
