Abstract
In this work, we investigate the evolution of magnetic domains with time in magnetic auxetic systems using the Ising model. We show that the mechanical deformation of the structure affects the way how domains evolve and that their rate of growth does not follow a well‐known power law associated with the Ising model for systems corresponding to a specific distance between Ising spins. We also show that the variation in the rate of deformation of the system leads to completely different results in terms of the change in size of magnetic domains and domain energy. This means that upon changing the speed used to deform the system, it is possible to control the growth of magnetic domains and hence control the magnetic properties of the whole system. This may prove to be very important in the case of potential applications such as magnetic freezers where the magnetocaloric effect resulting with a change in temperature could be affected by the rate of deformation of the discussed auxetic structure.
