STRETCHED AND COMPRESSED – QUANTUM MATERIALS UNDER EXTREME CONDITIONS

By |2024-11-12T11:54:44+00:00November 12th, 2024|SCI Highlights|0 Comments

J. F. Linnartz, A. Kool, S. Wiedmann, HFML Nijmegen and IMM Radboud. Quantum materials often exhibit remarkable sensitivity to subtle changes in their physical environment, a feature that can unlock new functionalities and drive innovative applications. One key phenomenon is magneto-elastoresistance, where the electrical resistance of a metal in a [...]

OPTICAL READOUT OF SINGLE-MOLECULEMAGNETS MAGNETIC MEMORIES WITH UNPOLARIZED LIGHT

By |2024-11-12T11:11:33+00:00November 12th, 2024|SCI Highlights|0 Comments

Cyrille Train and Matteo Atzori, LNCMI-Grenoble. Magnetic materials are widely used for many technologies in areas such as energy, health, transportation, computation, and data storage. For the latter, the readout of the magnetic state of a medium is crucial. Optical readout based on the magneto-optical Faraday effect was commercialized, but [...]

QUANTUM INTERFERENCE BETWEEN QUASI-2D FERMI-SURFACE SHEETS IN UTe2

By |2024-08-27T12:39:24+00:00August 27th, 2024|SCI Highlights|0 Comments

Alex Eaton, University of Cambridge, UK and Yurii Skourski, HLD. Scientists from the UK, USA, Czech Republic, and Germany have studied the Fermi surface of the heavy-fermion superconductor UTe2. This material is of particular interest given its high likelihood of hosting a spin-triplet Cooper-pairing mechanism. Evidence for this stems primarily [...]

POSSIBLE METAMAGNETISM IN THE HIGHPRESSURE TETRAGONAL PHASE OF UTe2

By |2024-10-14T10:16:26+00:00August 27th, 2024|SCI Highlights|0 Comments

Tristan Thebault, William Knafo, LNCMI Toulouse, Daniel Braithwaite, Gérard Lapertot, Georg Knebel, CEA-Grenoble, and Dai Aoki, Tohoku University. The interplay between magnetism and unconventional superconductivity in UTe2 was extensively studied in the past few years. Multiple superconducting phases were found to be induced near to a metamagnetic transition under magnetic [...]

HIGH-FIELD NMR UNVEILS FIELD-REINFORCED SUPERCONDUCTIVITY IN UTe2

By |2024-08-27T11:45:11+00:00August 27th, 2024|SCI Highlights|0 Comments

Y. Tokunaga, Japan Atomic Energy Agency, Tokai, Japan, M. Horvatić and Steffen Krämer, LNCMI Grenoble. The uranium-based superconductor UTe2 provides an attractive platform for studying the novel physics of spin-triplet and topological superconductivity in bulk materials. Resistivity measurements performed in 2019 at LNCMI, both in continuous and pulsed fields, revealed that [...]

QUANTUM HALL EFFECT IN InAsSb QUANTUM WELLS AT ELEVATED TEMPERATURES

By |2024-08-27T11:02:49+00:00August 27th, 2024|SCI Highlights|0 Comments

Maurice Bal, HFML Nijmegen. Since its discovery in 1980 by von Klitzing et al., the quantum Hall effect (QHE) has been measured in many different 2D systems, mainly at cryogenic temperatures. Currently, graphene is the only material that displays the QHE at room temperature (RT). Considering that the robustness of [...]

POSSIBLE ORIGIN OF HIGH-FIELD REENTRANT SUPERCONDUCTIVITY IN UTe2

By |2024-06-11T09:25:14+00:00June 11th, 2024|SCI Highlights, Uncategorized|0 Comments

Toni Helm, HLD. The recent discovery of superconductivity (SC) in the heavy-fermion metal UTe2 with a critical temperature of about 2 K triggered much excitement, as its critical field reaches values approaching those of high-Tc superconductors. Moreover, UTe2 appeared very quickly as a potential candidate for topological spin-triplet SC that [...]

QUANTUM OSCILLATIONS IN THE SPECIFIC HEAT OF GRAPHITE REVEAL PHYSICS HIDDEN IN TEXTBOOKS

By |2024-06-11T07:09:23+00:00June 10th, 2024|SCI Highlights|0 Comments

Z. Yang, Y. Kohama, ISSP, University of Tokyo, Japan and D. K. Maude, LNCMI Toulouse. We have investigated quantum oscillations in the electronic specific heat, Cel, in natural graphite. The crossing of a single spin Landau level at the Fermi energy gives rise to a double-peak structure (Figure 1a). Crucially, [...]

Sandra Kleuskens, HFML Nijmegen and IMM Radboud, Daniela Wilson, IMM Radboud, and Hans Engelkamp, HFML Nijmegen. Researchers of HFML-FELIX and the Radboud University have determined the magnetic anisotropy of polystyrene in poly-ethyleneglycol polystyrene polymersomes by magnetic birefringence and transmission electron microscopy. The magnetic anisotropy found is only a small fraction [...]
