Step-induced unusual magnetic properties of ultrathin Co/Cu films: Ab initio study.
نویسندگان
چکیده
We have performed ab initio studies to elucidate the unusual magnetic behavior recently observed in epitaxial Co films upon absorption of submonolayers of Cu and other materials. We find that a submonolayer amount of Cu on a stepped Co/Cu (100) film changes dramatically the electronic and magnetic structure of the system. The effect is mainly due to hybridization of Co and Cu d-electrons when copper forms a “wire” next to a Co step at the surface. As a result, a non-collinear arrangement of magnetic moments (switching of the easy axis) is promoted. 75.70.Ak,75.70.-i Typeset using REVTEX

Investigation of effect of magnetic ordering on structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) using ab initio method
Structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) were studied for each of three magnetic configurations nonmagnetic, ferromagnetic, and antiferromagnetic by using density functional theory in generalized gradient approximations (GGA) and strong correlation correction (GGA + U). Due to magnetic transition from antiferromagnetic to nonmagnetic phase, an electr...
متن کاملSize effects and conductivity of ultrathin Cu films
We propose a model for the description of the transport properties of metallic films on a large scale of slab thickness. This model is based on solving the linearized Boltzmann equation in relaxation-time approximation using ab initio calculations within the framework of the density functional theory. The expression for the relaxation time is derived from the microscopic treatment of the scatte...
متن کاملEffect of Cobalt Concentration on Structural and Magnetic Properties of Co-Fe Thin Films
Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration levels. X-ray diffraction (XRD) was used to investigate the films crystal structures. The results indicate that if the Co concentration is less that the Fe concentration, the cubic structure appears in the films, while the hexagonal structure dominates when the C...

In this study, the effect o...
متن کاملAnisotropy in Magnetism
The enormous research on magnetic properties of ultrathin films and nanostructures produces also new activities in the fundamental understanding of the magnetic anisotropy energy (MAE) and the anisotropy of the orbital magnetic moment/atom. The pseudomorphic growth of Fe, Co, Ni on metallic and non-metallic substrates can change the nearest neighbor distance by ≈ 0.05 Å. This small change in st...
