Anisotropy is added to the Edwards-Anderson model in such a way that interactions along the x axis are stronger by a factor f with respect to other interactions. Hysteresis cycles for square and cubic ±J Ising spin glasses are obtained by Monte Carlo simulations. Concentration x of ferromagnetic interactions (-J), temperature T, and f are varied to study their effects on the characteristics of the hysteresis loops. Several behaviors are simulated and compared to experimental curves, finding similarities. Important aspects such as virgin curve, remnant magnetization, and coercive field are discussed in detail. It is found that anisotropy tends to stabilize spin-glass phases, leading to a larger remnant magnetization and larger coercive field.
