Superparamagnetic response of zinc ferrite incrusted nanoparticles
Journal of Alloys and Compounds(2015)
摘要
•Incrusted nanoparticles are found at the surface of ZnFe2O4 microparticles.•Magnetic contribution of nano and microparticles are analyzed by different models.•Langevin model is used to calculate the nanoparticles-superparamagnetic diameter.•Susceptibility and Langevin analysis and calculations agree with experimental data.
