Interlayer exchange coupling is a quantum mechanical phenomenon where the magnetic layers in a multilayer structure interact through a non-magnetic spacer, leading to either parallel or antiparallel alignment of their magnetizations. This coupling is crucial for the development of spintronic devices, as it influences the magnetic properties and functionalities of materials at the nanoscale.
