Abstract: We present high pressure resistivity at low temperature of NpS and NpSe systems up to 10 and 25 GPa respectively. These systems are reported as type II antiferro- magnets at 25 and 38 K respectively presenting bad metal aspects. In the magnetic domain, they present semiconducting features with high resistivity. When applying pressure, we observe an increase of TN from 25 to 50 K for NpS while magnetic order temperature decreases for NpSe from 38 K to 20 K.
