N2 - In an exchange coupled trained antiferromagnet (AF)-ferromagnet (FM) system, we could directly manipulate the uncompensated moments in the AF-resulting in inducing a magnetism within the AF layer. This is made possible by applying an in-plane magnetic field perpendicular to the cooling field H FC. Depth-sensitive polarized neutron scattering experiments in specular and off-specular mode have revealed that this interfacial manipulation could neither restore the untrained state nor could it reinduce the initial asymmetry in magnetization reversal. Our results demonstrate an initiative toward user defined exchange-coupled interfaces for the future.
