Kagome metals are exciting platforms to explore electronic instabilities such as charge density waves. The authors study here magnetotransport properties of various kagome compounds, with a focus on the wave metal ScV${}_{6}$Sn${}_{6}$ and explain characteristic features among them. For example, CsV${}_{3}$Sb${}_{5}$ both have waves, exhibit sublinear resistivity above ordering temperature anomalous Hall-like behavior below this temperature. This contrasts LuV${}_{6}$Sn${}_{6}$, which lacks...
The discovery of Yangshao Village stands as one the most significant archaeological findings in Chinese history. Its study, ongoing since last century, holds immense importance for understanding origins civilization. Swedish archaeologist Johan Gunnar Andersson played a pivotal role excavation site. Central to research is debate between Western origin theory and indigenous culture. Longshan culture serves evidence against theory. Through analysis, it becomes clear that both cultures are...
Metals with kagome lattice provide bulk materials to host both the flat-band and Dirac electronic dispersions. A new family of metals is recently discovered in AV6Sn6. The structures this material need more experimental evidence confirm. In manuscript, we investigate problem by resolving quantum oscillations electrical transport magnetization ScV6Sn6. revealed orbits are consistent band structure models. Furthermore, Berry phase a dominating orbit be around $\pi$, providing direct for...
We report the results of thermodynamic measurements in external magnetic field cubic Ce-based cage compounds CeT2Cd20(T= Ni,Pd). Our analysis heat-capacity data shows that Γ7doublet is ground state multiplet Ce3+ions. Consequently, for it can be theoretically shown Ruderman-Kittel-Kasuya-Yosida interaction between localized Ce moments mediated by conduction electrons, must vanish at temperatures much lower than energy separating doublet from first excited Γ8quartet. findings provide an...
Abstract In the recently discovered kagome metal CsV 3 Sb 5 , an intriguing proposal invoking a doped Chern insulator state suggests presence of small Fermi pockets hosting spontaneous orbital-currents and large orbital magnetic moments. While net thermodynamic magnetization is nearly insensitive to these moments, due their antiferromagnetic alignment, can be revealed by Zeeman effect, which shifts electron energies in fields with proportionality given effective g −factor. Here, we determine...
The spin-1/2 kagome Heisenberg antiferromagnets are believed to host exotic quantum entangled states. Recently, the report of 1/9 magnetization plateau and magnetic oscillations in a antiferromagnet YCu$_3$(OH)$_6$Br$_2$[Br$_x$(OH)$_{1-x}$] (YCOB) have made this material promising candidate for experimentally realizing spin liquid Here we present measurements specific heat $C_p$ YCOB high fields (up 41.5 Tesla) down 0.46 Kelvin, feature has been confirmed. Moreover, temperature dependence...
Abstract The thermal Hall effect recently provided intriguing probes to the ground state of exotic quantum matters. These observations transverse signals lead debate on fermionic versus bosonic origins these phenomena. recent report oscillations (QOs) in Kitaev spin liquid points a possible resolution. Landau level quantization would most likely capture only transport effect. However, QOs are generally hard detect. In this work, we observation large oscillatory correlated Kagome metals. We...
