Abstract

The effective field theory within a probability distribution technique that accounts for the self-spin correlation functions is used to study the magnetic properties of the ferromagnetic system described by the spin S= 1/2 Ising model. The thermal behaviors of magnetization and longitudinal hysteresis are examined in details to study the effects of shell on the magnetics properties in the nanoparticles.

Keywords:
