Abstract

We have studied magnetic and magnetotransport properties in fee (111)- and (211)-oriented [FeMn/Py/Cu/Pyl (Py= Ni80Fe20) films grown on Mo(110) and Mo(211) templates by molecular beam epitaxy. Uniaxial magnetic anisotropy of the magnetic layers in both cases were self-assembled by epitaxial growth. However, the pinned layer coercive fields of the (211) films were much higher than those of the (111) samples. For both orientations the optimal exchange field (∼130Oe) and magnetoresistance (∼3%) occur at substrate temperature of∼170°C, about 30-40°C above the blocking temperature of FeMn layer.
