Abstract

The resistivity ρ and Hall resistivity ρH are measured on FeSe at pressures up to P=28.3 kbar in magnetic fields up to B=14.5 T. The ρ(B) and ρH(B) curves are analyzed with multicarrier models to estimate the carrier density and mobility as a function of P and temperature (T≤110 K). It is shown that the pressure-induced antiferromagnetic transition is accompanied by an abrupt reduction of the carrier density and scattering. This indicates that the electronic structure is reconstructed significantly by the antiferromagnetic order.
