    "abstract": "We have used the Stern-Gerlach deflection technique to study magnetism in\nchromium clusters of 20-133 atoms. Between 60 K and 100 K, we observe that\nthese clusters have large magnetic moments and respond superparamagnetically to\napplied magnetic fields. Using superparamagnetic theory, we have determined the\nmoment per atom for each cluster size and find that it often far exceeds the\nmoment per atom present anywhere in the bulk antiferromagnetic lattice.\nRemarkably, our cluster beam contains two magnetically distinguishable forms of\neach cluster size with \u003e= 34 atoms. We attribute this observation to structural\nisomers.",
