摘要：
We stud in this paper the resistivity encountered by Ising itinerant spins traveling in the so-called J(1) - J(2) frustrated simple cubic Ising lattice. For the lattice, we take into account the interactions between nearest-neighbors and next-nearest-neighbors, J(1) and J(2) respectively. Itinerant spins interact with lattice spins via a distance-dependent interaction. We also take into account an interaction between itinerant spins. The lattice is frustrated in a range of J(2) in which we show that it undergoes a very strong first-order transition. Using Monte Carlo simulation, we calculate the resistivity rho of the itinerant spins and show that the first-order transition of the lattice causes a discontinuity of rho.
