Influence of the Interface State on the Magnetoresistive Properties of Co/Cu Superlattices

The influence of the interface structure on the magnetoresistive properties of Co/Cu superlattices has been studied using the techniques of nuclear magnetic resonance and X-ray reflectivity. It has been found that the roughness of interfaces and the number of cobalt atoms involved in their formation increase with annealing temperature, while the fraction of highly perfect interfaces decreases at higher temperatures. It has been demonstrated that the probability of the scattering of conduction electrons by interfaces increases with the width of these boundaries.

Theoretical DFT Study of Atomic Structure and Spin States of the Cox(C60)n (x = 3−8, n = 1,2) Complex Nanoclusters

Atomic structure and spin states of a set of Cox and Cox(C60)n (x = 3−8, n = 1, 2) clusters are studied using a sophisticated ab initio GGA calculations. It is shown that high-spin low-symmetry structure of free-standing Cox clusters is determined by Jahn−Teller distortions. Formation of η2, η2′ or η1 coordination bonds between Cox fragment and C60 molecules through carbon hexagons results in stable complex nanoclusters with nonmonotonic change of average spin momentum upon the number of cobalt atoms in the Cox cores. The theoretical results are compared with corresponding experimental data.
