The core is occupied by spin-1/2 magnetic atoms, while those surrounding the inner shell sites are occupied by spin-1 diluted magnetic atoms and the outer shell sites are occupied by spin-3/2 magnetic atoms. The temperature and composition dependence of the hysteretic properties is investigated, and the roles of crystal field and composition are discussed. The interesting phenomenon of the inverted hysteresis loop has been found. The results show magnetic properties of the ternary nanoparticles system strongly depend on the composition of the inner shell. Moreover, core–shell interactions are proposed as the basic factors affecting the magnetic properties of the ternary nanoparticles system.
