Query: Towards understanding of magnetization reversal in Nd$-$Fe$-$B
  nanocomposites: Analysis by high-throughput micromagnetic simulations   We demonstrate how micromagnetic simulations can be employed in order to
characterize and analyze the magnetic microstructure of nanocomposites. For the
example of nanocrystalline Nd$-$Fe$-$B, which is a potential material for
future permanent-magnet applications, we have compared three different models
for the micromagnetic analysis of this material class: (i) a description of the
nanocomposite microstructure in terms of Stoner-Wohlfarth particles with and
without the magnetodipolar interaction; (ii) a model based on the core-shell
representation of the nanograins; (iii) the latter model including a
contribution of superparamagnetic clusters. The relevant parameter spaces have
been systematically scanned with the aim to establish which micromagnetic
approach can most adequately describe experimental data for this material.
According to our results, only the last, most sophisticated model is able to
provide an excellent agreement with the measured hysteresis loop. The presented
methodology is generally applicable to multiphase magnetic nanocomposites and
it highligths the complex interrelationship between the microstructure,
magnetic interactions, and the macroscopic magnetic properties.
