Abstract
This review is divided into two main parts, with the common theme of nanocrystalline metallic magnetic alloys. The first part will introduce soft magnetic materials and describe how nanocrystalline magnetic materials perform in this capacity. The discussion will include ways of improving the performance of a special nanocrystalline soft magnet designed to operate at high temperatures. The second part will introduce the concept of a magnetocaloric effect and how it can be used to produce a magnetic refrigerator. Recent materials advances have opened the possibility that magnetic refrigerators can be made to operate usefully at temperatures well above 0 K, perhaps even near room temperature. Nanocrystalline magnetic materials, engineered to display superparamagnetic behavior, are one of two classes of materials that can display such an enhanced magnetocaloric effect.Citation
