Abstract

The aim of this paper is to investigate a new type of magnetic material, which has a permanent random exchange interaction. The ferromagnetic properties (magnetizations) of an Ising nanostructure are investigated using the effective field theory with correlations. The system has consisted from spin-1/2 atoms with a random exchange interaction Jij. The value of Jij is randomly distributed by a random function. A specific investigation about the special effects of the random core exchange interaction on the magnetization and the critical temperature has been studied. For the appropriate value of the system parameter new descriptions and phenomena of the magnetizations in 3D have been obtained. The results show that it is possible to get the same ferromagnetic behavior observed with a constant exchange interaction by using a permanent random exchange interaction. Moreover, the results found can be as well displayed in three dimensions (3D) with the same behavior observed in 2D. The results are well detailed in the paper.
