Abstract
A novel quartz-fiber torsion balance is employed to make magnetic measurements on individual microscopic ferrite particles. A very direct experimental test provides strong evidence for the existence of single-domain magnetic particles. Further, the results confirm theoretical calculations of the critical single-domain size within a small factor.Keywords
