Abstract

PrSb₂ exhibits a charge-density wave (CDW) transition at T_CDW = 100 K and antiferromagnetic (AFM) ordering at T_N = 5 K at ambient pressure. Hall resistivity measurements revealed an anomalous feature within the AFM state, which was attributed to the topological Hall effect (THE), ruling out contributions from the ordinary and anomalous Hall effects. Significantly, the THE anomaly diminished with increasing pressure and almost vanished as the CDW transition was suppressed near the critical pressure P_c = 1.0 GPa. These findings suggest a relationship between the CDW order and the appearance of the THE in PrSb₂.
