NuMagSANS – Example 3: MuMax3-Based Simulation Pipeline for an Ensemble of Iron Nanoparticles with Vortex Spin Textures

This repository provides the simulation and post-processing pipeline for modeling a dilute ensemble of spherical iron nanoparticles with cubic magnetocrystalline anisotropy using MuMax3 and the NuMagSANS framework.The code automates hysteresis-loop simulations over a set of random magnetic-field orientations and applies a back-rotation procedure to emulate random anisotropy axes.Each simulation represents a single, decoupled nanoparticle; the ensemble behavior is reconstructed statistically by averaging over all orientations.This approach suppresses artificial anisotropies caused by discretization effects and provides reproducible reference data for benchmarking NuMagSANS and related magnetic small-angle neutron scattering (SANS) analyses.All scripts and input files required to reproduce the simulations are included.
