| Abstract: | The exchange interaction among metal spherical clusters had been discussed by means of RKKY theory. And the relation effect between the magnetic properties of Fe n clusters systems embeded in zeolite molecule-sift and the clusters dimension had been investigated by Monte Carlo simulation. It was shown that the magnetic properties of embeded clusters system oscillated with the distance between clusters, and its magnetization increased with the increasing of clusters density and fill efficiency. The results provided a guide for preparing new magnetic composite materials. |
