In-Plane Ferromagnetism and Critical Dynamics in Alkali-Deficient K $_{1 - x}$ CrTe $_{2}$ (with $x \approx$ 0.3) Single Crystals

Catherine Witteveen, Felix Eder, Sara A. LÃ³pez-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 K $_{1 - x}$ CrTe $_{2}$ s…

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…

Discovery of the Type-II Superconductor Ta $_{4}$ Rh $_{2}$ C $_{1 - I^´}$ with a High Upper Critical Field

KeYuan Ma, Sara LÃ³pez-Paz, Karolina Gornicka +3

We report on the discovery of superconductivity in the previously unknown compound Ta $_{4}$ Rh $_{2}$ C $_{1 - I^´}$ . Ta $_{4}$ Rh $_{2}$ C $_{1 - I^´}$ crystallizes in the $I^\cdot$ -carbide structure type, i…

Controlling the Magnetic Properties of the van der Waals Multiferroic Crystals Co $_{1 - x}$ Ni $_{x}$ I $_{2}$

Anastasiia Lukovkina, Sara A. Lopez-Paz, Celine Besnard +3

The structurally related compounds NiI $_{2}$ and CoI $_{2}$ are multiferroic van der Waals materials, in which helimagnetic orders exist simultaneously with electric polarization. Here,…
