Abstract

Second-harmonic generation magneto-optic Kerr effect (SHMOKE) experiments, sensitive to buried interfaces, were performed on a polycrystalline $\chem{FeMn/NiFe}$ bilayer in which areas with different exchange bias fields were prepared using 5 $\un{keV}$ $\chem{He}$ ion irradiation. Both reversible and irreversible uncompensated spins, localized and measured in the antiferromagnetic layer close to the interface with the ferromagnetic layer, are related to the exchange bias field.
