摘要：
In this paper we report on some ground-state properties of the spin-1/2, Heisenberg antiferromagnet on the two-dimensional square-kagome lattice. Finite N-spin systems were investigated with the use of the resonating valence bond method. Like in the case of spin system on kagome lattice we find the almost flat dependence of mean singlet length on 1/N.
