Available in PDF, EPUB and Kindle. Book excerpt: In this thesis properties of thin films of the frustrated antiferromagnet IrMn3 (chemically ordered phase) are examined using Metropolis Monte Carlo simulations, which is a step towards a better understanding of the exchange bias phenomenon in heterostructures with this material. This fcc compound has an unusual magnetic structure composed of ABC stacked (along cubic h111i axes) kagome layers of magnetic Mn ions. The kagome lattice is known to exhibit a high degree of frustration for antiferromagnetically coupled spins. A classical spin Heisenberg Hamiltonian is utilized, where symmetry breaking at the surfaces is modeled by introducing a local easy axis anisotropy perpendicular to the film. The impact of having an easy-axis anisotropy on the surface layers and cubic anisotropy in the middle layers is explored. The spin structure at the surface is shown to be different from that of the bulk 3D system, where spins tend to align along the surface [111] normal axis. This alignment tendency then propagates to the middle layers through exchange coupling. Results are shown for the specific heat, magnetization and sub-lattice order parameters for both surface and middle spins in three and six layer films as a function of increasing axial anisotropy. Preliminary results of simulations of the thin films with surface magnetic vacancies, which usually is present in real films, are also shown.

Book excerpt: In this paper we discuss the use of atomistic Monte Carlo simulations to predict film microstructure evolution. We discuss physical vapor deposition, and are primarily concerned with films that are formed by the nucleation and coalescence of 3D islands. Multi-scale modeling is used in the sense that information obtained from molecular dynamics and first principles calculations provide atomic interaction energies, surface and grain boundary properties and diffusion rates for use in the Monte Carlo model. In this paper, we discuss some fundamental issues associated with thin film formation, together with an assessment of the sensitivity of the film morphology to the deposition conditions and materials properties.

Download or read book Magnetostatic Modelling of Thin Layers Using the Method of Moments And Its Implementation in OCTAVE/MATLAB written by Roman Szewczyk and published by Springer. This book was released on 2018-04-10 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an efficient and robust method of modelling the magnetostatic properties of different technical elements, especially thin layers for magnetic sensors. The solutions presented utilise the principles of the method of moments. However, the principles have been developed both from the point of view of physical analyses as well as from the point of view of numerical optimisation. To enable cost-efficient use of the solutions for commercial applications in industry, the proposed method was implemented as a code optimised for use in the open-source OCTAVE environment. The scripts can be also used with MATLAB software, which is more user friendly, especially for less experienced users.

Download or read book Monte Carlo Study of Fluctuations and Magnetization Reversal in Nickel-iron Ferromagnetic Ultra-thin Films written by Adebanjo Akinwummi Oriade and published by ProQuest. This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a Monte Carlo simulation study of fluctuations and magnetization reversal in thin (5, 10 and 20 nanometers thin), permalloy (Ni 81 Fe 19 films. The study shows how the presence of vertical end pinned domains (VEPDs) in these films leads to nucleation of vortices and anti-vortices. We also show how the vertical edge pinned domains (VEPDs) lead to the formation of horizontal edge pinned domains (HEPDs) in the course of a films magnetization reversal. A mechanism for HEPD-reversal is discovered, involving the creation and motion of a head-to-head domain wall. When vortices nucleate to initiate a films magnetization reversal the switching field varies linearly with temperature, and for reversal that starts with growth of VEPDs switching field has a T 2 dependence. Novel images of spin configuration are used to show fluctuations and magnetization reversal. Our thin film's easy-axis is parallel to the length of the film. For a 5 nm thin film, the author shows that roughness in the edges parallel-to-the-easy-axis increases the switching field of the film in comparison to the switching field of a control film--a similar film with straight edges--by 3.9% in an aspect ratio 5 film and by 6.7% in an aspect ratio 1.5 film. When roughness, or etching, is in the edges perpendicular-to-the-easy-axis the switching field of such films is less than that of the control film by 2.8% and by 4.2% in the respective cases. The mechanisms described in this work are of importance in computer memory and data-storage industry, as well for sensor and circuit isolator applications.
