We discuss the ground state, the low-lying excitations as well as high-field thermodynamics of the Heisenberg antiferromagnet on the two-dimensional square-kagom´e lattice. This magnetic system belongs to the class of highly frustrated spin systems with an infinite non-trivial degeneracy of the cl...
