Magnetic field effects on the pressure-induced colossal maximum in electrical resistivity of CeSb

Pressure-induced sharp maximum in electrical resistivity ρ( T) of CeSb is observed near 35 K at pressures above 1.5 GPa . The peak value increases rapidly in proportion to the square of pressure up to 6 GPa , and at 7 GPa it reaches a value nearly 23 times as large as that at ambient pressure. We ha...

Summary:Pressure-induced sharp maximum in electrical resistivity ρ( T) of CeSb is observed near 35 K at pressures above 1.5 GPa . The peak value increases rapidly in proportion to the square of pressure up to 6 GPa , and at 7 GPa it reaches a value nearly 23 times as large as that at ambient pressure. We have measured ρ( T) curves of CeSb at 4 GPa under various fixed magnetic fields up to 16 T . The peak value of this colossal maximum exhibits a very rapid decrease with increasing magnetic field and this peak disappears completely above 6 T . This result strongly suggests that the cause of the colossal maximum is attribute to some magnetic origin.
