Magnetic anisotropy, interlayer coupling, and magneto-optical effects in single-crystalline Fe/Cr/Fe/MgO/Fe magnetotunnel structures grown on GaAs(001) substrates ( Article No. 113905)

Abstract
Fe/MgO/Fe single-crystalline magnetotunneling structures were epitaxially grown on GaAs(001). An independent magnetization switching in the Fe electrodes was achieved by pinning the magnetization of the Fe-top electrode by antiferromagnetic coupling across a Cr spacer to another Fe film.
Such Fe/Cr/Fe/MgO/Fe/GaAs(001) structures exhibit in-plane anisotropy, which ensures a discrete switching behavior of magnetization simplifying the shape of the hysteresis loop.
