Experimental identification of pairing mechanism in unconventional superconductors is challenging. Here, Wuet al. show that the field dependence of the pairing strength influences the superconducting upper critical field in UCoGe, suggesting the domi

Fine-tuning chemistry by doping with transition metals enables new perspectives for exploring Kitaev physics on a two-dimensional (2D) honeycomb lattice of α-RuCl3, which is promising in the field of quantum information protection and quantum comput

Thermal transport of the frustrated spin-chain mineral linarite: Magnetic heat transport and strong spin-phonon scattering

Autor: Matthias Gillig, Xiaochen Hong, Piyush Sakrikar, Gaël Bastien, A. U. B. Wolter, Leonie Heinze, Satoshi Nishimoto, Bernd Büchner, Christian Hess

The mineral linarite (PbCuSO$_4$(OH)$_2$) forms a monoclinic structure where a sequence of Cu(OH)$_2$ units forms a spin-$\frac{1}{2}$ chain. Competing ferromagnetic nearest-neighbor ($J_1$) and antiferromagnetic next-nearest-neighbor interactions ($

Magnetic anisotropy and low-field magnetic phase diagram of the quasi-two-dimensional ferromagnet Cr2Ge2Te6

Autor: Gaël Bastien, Saicharan Aswartham, Bernd Büchner, Anja U. B. Wolter, S. Selter

Publikováno v: Physical Review B. 101

All known quasi-two-dimensional ferromagnets, such as $(X=\mathrm{Br},\mathrm{I})$ or ${\mathrm{Cr}}_{2}{(\mathrm{Ge},\mathrm{Si})}_{2}{\mathrm{Te}}_{6}$, exhibit a peculiar temperature dependence of the magnetization under small magnetic fields appl

Superconductivity is a unique manifestation of quantum mechanics on a macroscopic scale, and one of the rare examples of many-body phenomena that can be explained by predictive, quantitative theories. The superconducting ground state is described as
