Abstract
The influence of PVP on the magnetic properties of NiSn nanoparticles prepared by polyol method has been studied. NiSn nanoparticles exhibit superparamagnetic behavior although there is a ferromagnetic contribution due to particles agglomerated below the blocking temperature. The particle size is controlled by the addiction of PVP in varying amounts. The addition of PVP also favours the particles isolation, narrow the particle size distribution and decrease the interparticle interaction strength increasing the superparamagnetic contribution.
► NixSny alloys nanoparticles have been prepared by polyol method. ► NiSn nanoparticles exhibit superparamagnetic behavior. ► The PVP addition favours the particles isolation.
