摘要

The magnetic behavior of the hybrid heterostructures Fe(001)/ZnSe(001)/Fe(001) grown on ZnSe(001) epilayers on GaAs(001) substrates by molecular beam epitaxy was investigated by SQUID magnetometry. Three different thicknesses of the ZnSe spacer layer were used to investigate the magnetic coupling between 200 Angstrom thick Fe layers. Our results indicate the existence of an effective exchange bias field of about 5 Oe possibly originating from a residual antiferromagnetic coupling through 50 Angstrom thick ZnSe layer.
