Abstract

We studied the magnetoresistance of RTiO3 (R=Pr and Ce) with offstoichiometry as a doped Mott-Hubbard system and found positive magnetoresistance proportional to the absolute value of the magnetic field in the antiferromagnetic phase of both insulating and metallic samples. This result indicates that not only the coherent state that appears with doping and is responsible for the metallic conduction, but also the incoherent state of the Mott-Hubbard insulator is affected by the spin configuration.
