57Fe Mössbauer study of NiFe2O4 nanoparticles produced by the levitation-jet aerosol technique

Abstract

For the first time, Mössbauer parameters of mixed cubic spinel NiFe2O4 nanoparticles, prepared by using a one-stage process via evaporation of levitating iron-nickel droplets into a mix of helium-air gas flow accompanied with the application of a DC electric field of up to 210 kVm-1 , are reported.
