Title: The frustrated Heisenberg antiferromagnet: collinear versus noncollinear magnetic ordering
Abstract: We investigate the frustrated spin-12 Heisenberg antiferromagnet on the square lattice with 16 sites. We find, that collinear antiferromagnetic order is strongly suppressed by frustration. However, in the region of strong frustration noncollinear ordering arises which can be well described by an operator measuring the chirality of plaquettes.
