摘要
We demonstrate the effects and role of anisotropy and particle size distributions upon the values of constitutive parameters determined from experimental M(H) loops of single domain nanoparticle systems. We employ experimental and magnetic material parameters as inputs to a numerical programme run from a graphical user interface (GUI) to permit modelling and interpretation of experimental data and assessment of the stability of the constitutive parameters so derived and characterisation of the departures observed from pure Langevin behaviour.
