In-Plane Ferromagnetism and Critical Dynamics in Alkali-Deficient KCrTe (with 0.3) Single Crystals
Catherine Witteveen, Felix Eder, Sara A. López-Paz +6
Layered chromium tellurides are model systems for studying low-dimensional magnetism in van der Waals materials. We report the synthesis and characterization of KCrTe s…
Discovery of the Type-II Superconductor TaRhC with a High Upper Critical Field
KeYuan Ma, Sara López-Paz, Karolina Gornicka +3
We report on the discovery of superconductivity in the previously unknown compound TaRhC. TaRhC crystallizes in the -carbide structure type, in t…
Disentangling pre-transitional fluctuations in metallic VO2
Javier del Valle, Carl Willem Rischau, Artem Korshunov +8
VO2 features concomitant structural and metal-insulator transitions. This poses a challenge for understanding the underlying mechanism: is the transition triggered by a structural…
Controlling the Magnetic Properties of the van der Waals Multiferroic Crystals CoNiI
Anastasiia Lukovkina, Sara A. Lopez-Paz, Celine Besnard +3
The structurally related compounds NiI and CoI are multiferroic van der Waals materials, in which helimagnetic orders exist simultaneously with electric polarization. Here,…
Influence of magnetism on vertical hopping transport in CrSBr
Xiaohanwen Lin, Fan Wu, Sara A. Lopéz-Paz +4
We investigate the c-direction conduction in CrSBr in the linear regime, not accessible in other van der Waals (vdW) magnetic semiconductors, because of the unmeasurably low curren…
Anomalous T-dependence of phonon lifetimes in metallic VO2
Carl Willem Rischau, Artem Korshunov, Volodymyr Multian +9
We investigate phonon lifetimes in VO2 single crystals. We do so in the metallic state above the metal-insulator transition (MIT), where strong structural fluctuations are known to…
Structural Phase Transition and Superconductivity in 2H-BaGaGe with Buckled Honeycomb Layers
Dorota I. Walicka, Robin Lefevre, Olivier Blacque +5
We report on the structural and superconducting properties of the intermetallic compound BaGaGe. We find that this material undergoes a structural second-order phase transition fro…
Synthesis and Anisotropic Magnetic Properties of LiCrTe Single Crystals with a Triangular-Lattice Antiferromagnetic Structure
Catherine Witteveen, Elisabetta Nocerino, Sara A. López-Paz +4
We report on the synthesis of LiCrTe single crystals and on their anisotropic magnetic properties. We have obtained these single crystals by employing a Te/Li-flux synthesis me…
Dynamic Magnetic Crossover at the Origin of the Hidden-Order in van der Waals Antiferromagnet CrSBr
Sara A. López-Paz, Zurab Guguchia, Vladimir Y. Pomjakushin +6
The van der Waals material CrSBr stands out as a promising two-dimensional magnet. Especially, its high magnetic ordering temperature and versatile magneto-transport properties mak…
Quasi 1D electronic transport in a 2D magnetic semiconductor
Fan Wu, Ignacio Gutiérrez-Lezama, Sara A. Lopéz-Paz +6
We investigate electronic transport through exfoliated multilayers of CrSBr, a 2D semiconductor that is attracting attention because of its magnetic properties. We find an extremel…
