Abstract
Our proposed spin valve prototype showcases a sophisticated design featuring a two-dimensional graphene bilayer positioned between layers of ferromagnetic insulators. In this model, proximity coupling plays a pivotal role, influencing the magnetization orientations of the graphene layers and significantly impacting the \textit{in-plane} conductivity of the layers. In this present work, we position the graphene bilayer between two layers of the ferromagnetic insulator to establish this configuration. Using density functional theory, we conduct detailed computations to analyze the electronic structure of this sandwiched system. Our findings reveal a notable finite gap at specific \textit{k}-points, particularly evident in the antiparallel configuration of the magnetizations. This finding represents a significant advancement in spintronics, underscoring the potential of our spin valve prototype to drive innovation in electronic device technologies.
