Abstract
We report the high-field magnetization and longitudinal magnetoresistance measurements in magnetic fields of up to 55 T, and Hall resistivity and transverse magnetoresistance measurements in fields of up to 15 T for single crystals of CeRhSb with a pseudogap in the density of states. The magnetization at 1.3 K shows rather weak anisotropy along the orthorhombic principal axes, M a ≃ M b > M c , and the initial straight lines deviate upward near magnetic field values of 20, 30 and 25 T, respectively. The longitudinal magnetoresistance at 1.3 K is largely negative for both B // a and B // b and saturates near 30 T, while that for B // c is positive. The transverse magnetoresistance is positive and increases in proportion to B 1.5 for B // c , while those for B // a and B // b saturate at around 10 T. The Hall coefficient for B // a changes sign from positive to negative below 4 K, while that for B // c progressively increases with decreasing temperature. The Hall resistivity for B // a and B // b possesses,...
