Tracing the horizon of tetragonal-to-monoclinic distortion in pressurized trilayer nickelate La4Ni3O10
Sitaram Ramakrishnan, Yingzheng Gao, Valerio Olevano +18
The crux of understanding the superconducting mechanism in pressurized Ruddlesden-Popper nickelates hinges on elucidating their structural phases. Under ambient conditions, the tri…
Laser patterning of the room temperature van der Waals ferromagnet 1-CrTe
Tristan Riccardi, Suman Sarkar, Anike Purbawati +19
Lamellar crystalline materials, whose layers are bond by van der Waals forces, can be stacked to form ultrathin artificial heterostructures, and in particular vertical magnetic jun…
Magnetic imaging under high pressure with a spin-based quantum sensor integrated in a van der Waals heterostructure
Z. Mu, J. Fraunié, A. Durand +15
Pressure is a powerful thermodynamic parameter for tuning the magnetic properties of van der Waals magnets owing to their weak interlayer bonding. However, local magnetometry measu…
Comparative study of magnetic quantum oscillations in Hall and transverse magnetoresistance
A. A. Sinchenko, P. D. Grigoriev, A. V. Frolov +5
Magnetic quantum oscillations (MQO) of Hall coefficient are measured in rare-earth tritelluride TmTe and shown to be much stronger and persist to higher temperature than the…
Charge-Density-Waves Tuned by Crystal Symmetry
A. Gallo-Frantz, A. A. Sinchenko, D. Ghoneim +10
The electronic orders appearing in condensed matter systems are originating from the precise arrangement of atoms constituting the crystal as well as their nature. This teneous rel…
Stability of the In-Plane Room Temperature van der Waals Ferromagnet Chromium Ditelluride and Its Conversion to Chromium-Interleaved CrTe Compounds
Anike Purbawati, Suman Sarkar, Sébastien Pairis +19
Van der Waals magnetic materials are building blocks for novel kinds of spintronic devices and playgrounds for exploring collective magnetic phenomena down to the two-dimensional l…
Collective magnetic state induced by charge disorder in the non-Kramers rare-earth pyrochlore TbScNbO
Y. Alexanian, E. Lhotel, R. Ballou +15
Geometrical frustration, as in pyrochlore lattices made of corner-sharing tetrahedra, precludes the onset of conventional magnetic ordering, enabling the stabilization of fluctuati…
Possible high temperature superconducting transitions in disordered graphite obtained from room temperature deintercalated KC
Samar Layek, Miguel Monteverde, Gastón Garbarino +13
Although progress with twisted graphene nano-devices is boosting the superconductivity that is the consequence of their Moiré flat electronic bands, the immense choice for future d…
Kitaev interactions in the Co honeycomb antiferromagnets NaCoSbO and NaCoTeO
M. Songvilay, J. Robert, S. Petit +10
Co ions in an octahedral crystal field, stabilise a j = 1/2 ground state with an orbital degree of freedom and have been recently put forward for realising Kitaev in…
Characterization of room-temperature in-plane magnetization in thin flakes of CrTe with a single spin magnetometer
F. Fabre, A. Finco, A. Purbawati +5
We demonstrate room-temperature ferromagnetism with in-plane magnetic anisotropy in thin flakes of the CrTe van der Waals ferromagnet. Using quantitative magnetic imaging with…
In-plane magnetic domains and Néel-like domain walls in thin flakes of the room temperature CrTe van der Waals ferromagnet
Anike Purbawati, Johann Coraux, Jan Vogel +17
The recent discovery of magnetic van der Waals materials has triggered a wealth of investigations in materials science, and now offers genuinely new prospects for both fundamental…
Toward equilibrium ground state of charge density waves in rare-earth tritellurides
A. V. Frolov, A. P. Orlov, A. Hadj-Azzem +3
We show that the charge density wave (CDW) ground state below the Peierls transition temperature, , of rare-earth tritellurides is not at its equilibrium value, but depend…
Interplay between electron band-anticrossing and charge-density-wave instabilities
P. D. Grigoriev, A. A. Sinchenko, P. A. Vorobyev +4
Our measurements of the Hall coefficient in rare-earth tritelluride compounds reveal a strong hysteresis between cooling and warming in the low temperature range where a second uni…

We have studied the magnetic properties of NaCoTeO, which features a honeycomb lattice of magnetic Co ions, through macroscopic characterization and neutron diff…
Bilayer splitting versus Fermi-surface warping as an origin of slow oscillations of in-plane magnetoresistance in rare-earth tritellurides
Pavel D. Grigoriev, Alexander A. Sinchenko, Pascal Lejay +5
Slow oscillations (SlO) of the in-plane magnetoresistance with a frequency less than 4 T are observed in the rare-earth tritellurides and proposed as an effective tool to explore t…
