Spin reorientation transition of Fe films in magnetically coupled Fe/Cu/Ni/Cu(001) - art. no. 014409

摘要

Spin reorientation transition (SRT) of Fe film in the magnetically coupled Fe/Cu/Ni/Cu(001) system was investigated by surface magneto-optic Kerr effect and photoemission electron microscopy. We found that the Fe in-plane magnetic remanence within the SRT region oscillates with the Cu layer thickness with a periodicity exactly half of that of the magnetic interlayer coupling. Element specific domain imaging shows that the Fe stripe domains within the SRT region are washed away by the magnetic interlayer coupling in such a way that the majority domain size increases without changing the minority domain size. These results are discussed in terms of the virtual magnetic field produced by the magnetic interlayer coupling. [References: 23]
