| Abstract: | We use a variation of the Stern-Gerlach experiment to study the magnetic behavior of transition metal clusters. We report measurements of the magnetic properties of nickel clusters as a function of cluster size, vibrational temperature, and applied magnetic field. Results for these nickel clusters resemble those previously published for cobalt clusters in that superparamagnetic behavior is observed. As is the case for cobalt clusters, nickel clusters are observed to have magnetic moments per atom that are greater than the bulk value. |
