  We study magnetic phases of two-component mixtures of ultracold fermions with
repulsive interactions in optical lattices in the presence of hopping
imbalance. Our analysis is based on dynamical mean-field theory (DMFT) and its
real-space generalization at finite temperature. We study the temperature
dependence of the transition into the ordered state as a function of the
interaction strength and the imbalance parameter in two and three spatial
dimensions. We show that below the critical temperature for N\'{e}el order
mass-imbalanced mixtures also exhibit a charge-density wave, which provides a
directly observable signature of the ordered state. For the trapped system, we
compare our results obtained by real-space DMFT to a local-density
approximation. We calculate the entropy for a wide range of parameters and
identify regions, in which mass-imbalanced mixtures could have clear advantages
over balanced ones for the purpose of obtaining and detecting quantum
magnetism.
