Magnetic Properties of Fe-V Multilayered Films with Artificial Superstructures

Abstract

Multilayered films with artificial superstructures were synthesized by alternate deposition of Fe and V in ultrahigh vacuum. X-ray diffraction confirmed the establishment of artificial periodicities with very short wavelengths, e.g. Fe(4 Å)-V(8 Å) of the minimum case, and bcc [110] texture. Magnetic properties as a function of Fe layer thickness were studied from Mössbauer and SQUID measurements. Local magnetization at the Fe interface layer contacting with V is discussed from Mössbauer results on surface-selectively enriched samples and also from polarized neutron diffraction experiments.
