TL;DR: In this article, the magnetic behavior of nanocrystalline alloys has been modeled using atomic Monte Carlo simulation, and the mechanism of polarization of the matrix by fields penetrating from the nanograin is discussed and correlated with the matrix-nanograin exchange coupling.

TL;DR: In this article, a detailed analysis of the correlation between the microstructure of annealed samples and their magnetic properties is provided, with emphasis on the matrix-nanocrystalline grain interface which is shown to exhibit peculiar magnetic behavior.

TL;DR: In this article, the effect of surface anisotropy and vacancies upon the ground magnetic state of ferromagnetic nanoparticles is discussed, based on a random site-diluted classical Heisenberg Hamiltonian with nearest neighbor interactions, surface and core anisotropies, and a Monte Carlo-Metropolis approach with simulated annealing for energy minimization.

TL;DR: In this article, the impact of varying the anisotropic constant parameter on the coercive field for different temperatures and algorithms is investigated. And the results reveal that the coercive force is linearly related to the ani-tial anisotropy provided that the algorithm and the numeric conditions are carefully chosen.
