MAGNETIC AND TRANSPORT-PROPERTIES OF EPITAXIAL FE V(001) SUPERLATTICEFILMS/

Single-crystalline Fe(15 ML)/V (1-12 ML) superlattices, epitaxially gr own in the (001) direction, have been investigated using magnetization and electrical transport measurements. For all V thicknesses the syst em exhibits ferromagnetic properties. Results from magnetization and h ysteresis measurements with the field applied in different directions confirm that the superlattice is well defined, the interface roughness is small, and the crystallinity of the samples is good A clear influe nce of the V thickness, due to strain effects, on the in-plane magneti c anisotropy is found. Resistivity measurements show that the samples exhibit anisotropic magnetoresistive (AMR) properties with a strong de pendence of the V thickness on the magnitude of the AMR.
