Abstract

High field magnetotransport measurements between 1.4 and 300 K and in applied magnetic fields to 18 T on Ce_1-xLa_xRhIn₅ series of compounds were performed. The measurements were done to gain a better understanding of the unusual heavy fermion ground state in CeRhIn₅. A sign change in the magnetoresistance at high temperature is reached by La concentration of 75%. The results showed a positive contribution in the magnetoresistance due to the coherent Kondo regime and a negative contribution due to more localized single impurity regime.
