Anomalous Hall Effect in a new Ce based Heavy Fermion Compound

Ce-based intermetallic compounds provide a rich platform for studying diverse magnetic states. These materials may host competing interactions arising from the Kondo effect, crystal electric field, and RKKY interactions. More recently, attention has been drawn to the possibility of the coexistence of strong correlations and topological features. In this talk, I will discuss the magneto-transport and thermodynamic properties of a new Ce based compound. Resistivity shows a Kondo-like behavior and specific heat shows a Sommerfeld coefficient γ ~ 100 mJ/molK², putting the compound in the moderate heavy fermion regime. Magnetization measurements reveal several metamagnetic transitions coinciding with those observed in magnetoresistance and Hall data. The Hall resistivity in the ordered state shows anomalous behavior, possibly attributed to nontrivial topology. These findings have the potential to enhance our understanding of the interplay between strong correlations and topology.
