A theoretical investigation on equilibrium magnetic properties in nanowire arrays

The paper focuses on the study of an Ising nanowire array composed of core/shell-structured single nanowires placed at the edges of a square lattice. The phase transition temperature, at which a transition occurs in the magnetic properties, is obtained using effective field theory for two interacting individual nanowires. To understand how the interaction affects the magnetic, we defined the exchange interaction (JR) between the single nanowires. This interaction is assigned both positive and negative values to reveal the ferromagnetic and antiferromagnetic characteristics of the system. Our results revealed that the exchange interaction between individual nanowires significantly influences the magnetic properties of the system.
