Reorientation Phase and Striped Domain Patterns of Thin Films

Abstract

A ferromagnetic monolayer with competing long-range dipolar interaction, short-range interaction and magnetic uniaxial anisotropy is studied using Monte Carlo simulation. Striped domain patterns are found and reveal the microstructure of the magnetization transition at the ground state via the competing between dipolar interaction and uniaxial anisotropy. We present the finite temperature phase diagram and find a temperature-induced magnetization reorientation from out-of-plane to in-plane phase. The influence of the various interactions on the structure of the striped phase and reorientation behavior has been discussed.

The roles of the exchange and dipole couplings on the magnetoresistance for the nanoparticle arrays

“…As a result, the coercivity increases and the value of TMR decreases with increasing value of J. However, for the system with strong dipolar interaction, the moments prefer orientating in x-y plane and the striped domain phase is produced [5][6][7][8]. As the magnetic field is applied along the x axis, the large dipolar interaction suppresses the anisotropy energy.…”

The Growth, Surface Topography and Curie Temperature in Ni Thin Films: Kinetic Lattice Monte Carlo Simulation

“…The magnetic films have become interesting subjects for novel technological applications and theories, such as giant magnetoresistance effect and its application in magnetic storage [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. It has been confirmed that the thickness and surface roughness influence significantly the magnetic properties of the films.…”
