    "abstract": "We investigate noncollinear effects in antiferromagnetically coupled clusters\nusing the general, rotationally invariant form of local spin-density theory.\nThe coupling to the electronic degrees of freedom is treated with relativistic\nnon-local pseudopotentials and the ionic structure is optimized by Monte-Carlo\ntechniques. We find that small chromium clusters (N \\le 13) strongly favor\nnoncollinear configurations of their local magnetic moments due to frustration.\nThis effect is associated with a significantly lower total magnetization of the\nnoncollinear ground states, ameliorating the disagreement between Stern-Gerlach\nmeasurements and previous collinear calculations for Cr_{12} and Cr_{13}. Our\nresults further suggest that the trend to noncollinear configurations might be\na feature common to most antiferromagnetic clusters.",
