High-field magnetism of Kondo semiconductors CeNiSn and CeRhSb

Abstract The longitudinal magnetoresistance of the Kondo semiconductor single crystals CeNiSn and CeRhSb are investigated up to 36 T below 4.2 K. Large negative magnetoresistances are found at low temperatures with the field along the b - and c -axis, similar to the field direction along the a -axis in the previous study.
