Probing Transport Phenomena in a Cr-based Kagome Compound

Kagome metals, with their distinctive band structures, provide a rich platform for studying correlated quantum phenomena. We investigate the transport properties of a Cr-based Kagome compound which has c-axis as easy axis and transition temperature around 10K. Here, we focus on the electrical and thermal Hall effects of the compound, exploring potential violations of the Wiedemann-Franz law. We will discuss our experimental approach aimed at enhancing measurement sensitivity and accuracy, along with the implications for understanding the underlying physics of this material.
