    • Abstract

       

      A systematic study of the magnetic properties of ultra-fine particles of Mn0.5Fe0.5Fe2O4 spinel system has been undertaken. The effect of temperature on the magnetic properties of particles and the ferrofluid has been studied. Analysis of the data yields information on the anisotropy constant, particle size distribution and superparamagnetic behaviour. The results are explained on the basis of existing theories.
