摘要
The Ising model with additional next-nearest neighbour (n.n.n.) interactions in generator of diamond-type hierarchical lattice is studied. It is found that phase transition occurs only when the nearest neighbour (n.n.) interaction K-1 and n.n.n. interaction K-2 fulfils a certain relation and the universal class of phase transition is not changed by the long-range interactions.
