Ferrofluids based on two types of hybrid particles Fe3O4/β-cyclodextrin were prepared: Using monodomain (below 60 nm) magnetite nanoparticles with (A) non-superparamagnetic (non-SPM) behaviour and (B) with superparamagnetic (SPM) behaviour. We found

The aim of the work was to investigate the influence of the co-precipitation processes on the magnetic properties, the shape and the surface oxidation of nano-sized magnetite particles. The literature data on the process chemistry are inconsistent. O

Selected highly homogeneous powders of Fe3O4 with different particle size on the nanometer scale (10±2 and 3±2 nm) obtained by soft-chemical methods were studied by Mossbauer spectroscopy. The study shows clearly the powerful possibilities of Mossb

The present work proposes a modification of the ferrite plating method for synthesizing ferrite thin films from aqueous solutions at low temperatures about 97°C. Our approach combines spin-spray deposition from aqueous solutions at low temperature w
