The data of article''Micromagnetic Simulation of μ MAG Standard Problem No. 3: Evaluating the Standard Dipole-Dipole Interaction''
Listed in ScienceDB
Cubic−shaped magnetic particles subjected to a dimensionless uniaxial anisotropy (Q = 0.1) aligned with one of the crystallographic axes provide an ideal system for investigating magnetic equilibrium states.
Description
In this system, three fundamental magnetization configurations are identified: (i) the flower state, (ii) the twisted flower state, and (iii) the vortex state. This problem corresponds to Standard Problem No. 3 proposed by the NIST Micromagnetics Modeling Group, widely adopted as a benchmark for validating computational micromagnetics methods.
In this work, we approach the problem using a computational method based on direct dipolar interactions, in contrast to conventional techniques that typically compute the demagnetizing field via finite difference-based Fast Fourier Transform (FFT) methods, tensor grid approaches, or finite element formulations. Our results are compared with established literature data, focusing on the dimensionless parameter λ = L/lex , where L is the cube edge length and lex is the exchange length of the material.

To analyze equilibrium state transitions, we systematically varied the size L as a function of the simulation cell number N and intercellular spacing a, determining the critical λ value associated with configuration changes. Our simulations reveal that the transition between the twisted flower and vortex states occurs at λ ≈ 8.45, consistent with values reported in the literature, validating our code (Grupo de Fı́sica da Matéria Condensada - UFJF), and shows that this standard problem can be resolved using only interaction dipolar of a direct way without the use sophisticated additional calculations.
