Artificial spin ices (ASI) are lattices comprising of magnetic islands that interact through dipolar coupling and approximate the behavior of naturally occurring bulk spin ice materials at room temperature. They exhibit novel excitations such as magnetic monopole excitation as a result of magnetic frustration emerging due to either geometric or configurational frustration. ASIs are also particularly interesting as they may have applications in computer memory and magnetic logic. In this work, we have developed a novel ASI based on a Kagome lattice with each motif comprising of paired magnetic islands. We have studied their energy landscape using standard Markov chain Monte Carlo simulations with parallel tempering. During the simulations, we tracked various thermodynamic parameters such as specific heat, and magnetic susceptibility of the lattices were able to identify three phase transitions. We will discuss these results along with lack of observation of any long-range order in our simulations.
