Topological Hall Effect in PrSb${}_2$

Abstract

PrSb${}_2$ exhibits a charge-density wave (CDW) transition at $T_{\mathrm{CDW}}=100$ K and antiferromagnetic (AFM) ordering at $T_{\mathrm{N}}=5$ 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 PrSb${}_2$.
