Recent calculations have indicated the possibility of large permanent magnetic moments for clusters of nonferromagnetic materials. Here we describe Stern-Gerlach measurements of aluminum, chromium, palladium, and vanadium clusters, none of which are ferromagnetic in the bulk. No deflections were observed in any of these systems. Upper limits of the magnetic moments are reported.
