LOCALLY COMMENSURATE CHARGEDENSITY WAVE WITH THREE-UNIT-CELL PERIODICITY IN YBa2Cu3Oy

By |2021-09-28T11:05:47+00:00September 28th, 2021|SCI Highlights|0 Comments

Igor Vinograd and Marc-Henri Julien, LNCMI Grenoble. The ubiquity of charge-density waves (CDW) in cuprate superconductors is now well established, but the mechanism responsible for their formation remains debated. The generic aspects of the microscopic structure of the CDW are not settled yet. In this work, we used 17O nuclear [...]

STRANGE METAL TRANSPORT IN THE ELECTRONIC NEMATIC FeSe1-xSx

By |2021-09-28T10:41:32+00:00September 28th, 2021|SCI Highlights, Uncategorized|0 Comments

Matija Čulo, Salvatore Licciardello, and Nigel Hussey, HFML. Researchers from HFML, UK, USA, and Japan have carried out a detailed magnetotransport study of the electronic nematic superconductor FeSe1-xSx that reveals key signatures of the so-called ‘strange metal’ behavior in vicinity of its nematic quantum critical point (QCP) xс ≈ 0.17. [...]

ELECTRIC QUADRUPOLAR CONTRIBUTIONS IN THE MAGNETIC PHASES OF UNi4B

By |2021-05-17T13:07:36+00:00May 17th, 2021|SCI Highlights|0 Comments

Tatsuya Yanagisawa, Hokkaido University and Sergei Zherlitsyn, HLD Dresden. Researchers from Japan and the Czech Republic, together with scientists from the HLD, have succeeded in identifying that electric quadrupoles play an important role in the magnetic order of the honeycomb-layer compound UNi4B. The scientists showed that these quadrupoles maintain their [...]

SPIN-VALLEY-SPLIT SHUBNIKOV-DE HAAS OSCILLATIONS IN WSe2 MONOLAYERS

By |2021-05-17T10:19:02+00:00May 17th, 2021|SCI Highlights|0 Comments

Banan Kerdi, Mathieu Pierre, Michel Goiran, and Walter Escoffier, LNCMI Toulouse.  Transition-metal dichalcogenides (TMDCs) are two-dimensional layered materials showing intriguing electronic properties, especially when thinned down to a single layer. We studied WSe2 monolayers fabricated at LNCMI-Toulouse through transport measurements. We measured the magnetoresistance at 4.2 K under pulsed magnetic [...]

THERMODYNAMIC SIGNATURE OF THE PUTATIVE ELECTRONIC-NEMATIC TRANSITION IN CeRhIn5

By |2021-05-17T07:12:43+00:00May 11th, 2021|SCI Highlights|0 Comments

Sanu Mishra, Albin Demuer, Ilya Sheikin, LNCMI Grenoble, and Dai Aoki, Tohoku University. Strongly correlated electron systems, such as high-temperature superconductors, iron-based superconductors, and heavy-fermion compounds, are of high experimental and theoretical interest. In these materials, unconventional superconductivity is believed to emerge near a quantum critical point. In addition, some [...]
