The response of fine-particle magnetic oxides to applied magnetic fields is of primary importance in several areas of applied physics, such as magnetic separation, magnetic fluid devices, and magnetic recording. It is also of fundamental interest. In this article contemporary research on the important properties of magnetic oxide particles is reviewed, including both applied and basic work. The microscopic and macroscopic properties of ferrimagnetic and antiferromagnetic fine-particle systems are considered. Special attention is paid to the physics of magnetization reversal mechanisms, surface effects, and the intrinsic properties of fine-particle magnetic oxides.
