抄録: Two dimensional Ising model was studied so as to investigate the properties of superparamagnetism in which interaction exists between clusters such as the case of melt-spun La-Fe alloys. Based on the theory of V dovichenko, the statistical properties of this model were investigated. Obtained Curie temperature are dependent of distance between clusters and cluster size. Curie temperature is nearing that of 2 - dimensional Ising square lattice with increase of cluster size while the system does not show phase transition when cluster-cluster distance is beyond critical length. It is supposed that this system involves both properties of 1 -dimension and 2 -dimension from the behavior of Curie temperature.
