We investigate the magnetotransport properties of the half-filled antiferromagnetic (AF) one-band Hubbard model under an external magnetic field using the single-site dynamical mean-field theory. Particular attention is paid to the mechanisms driving the magnetoresistivity (MR) behavior. We analyze the dependence of MR on temperature and the strength of the applied magnetic field, providing insights into the interplay between magnetic field–induced fluctuations and transport properties in AF systems.
