Abstract

The project is inserted in the study of new emerging phenomena in Materials Physics that result from the reduction of dimensionality. Special emphasis will be given to the magnetism in nano-structured systems, being mainly directed to propose new magnetic recording devices based on the movement of domain-walls. Computer simulations will be performed with state-of- the-art approaches for first principles calculations (using Quantum Mechanics) and spin dynamics (using Statistical Mechanics). In special, the combination of electronic structure calculations within the Kohn-Sham scheme for the Density Functional Theory (DFT), using the Real-Space- Linear-Muffin-Tin-Orbital in the Atomic-Sphere-Approximation (RS-LMTO-ASA) method, and spin dynamics calculations, using the Uppsala Atomistic Spin Dynamics (UppASD) code,will constitute the theoretical tools of the work. As an initial system, Co/Irn/Pt (111) (n = 0, 1, &, 6) multilayers will be studied. At a later stage, with the acquired experience, other similar multilayers, such as Ni/Irn/Pt(111) and Co/Run/Pt(111), will be investigated. (AU)
