Magnetization in High Magnetic Field and Critical Magnetic Behaviour in Nanostructured Magnetic Oxides

  • I. Nedkov
Part of the NATO Science Series book series (NAII, volume 8)

Abstract

The unique magnetic properties of small oxide particles have generated increasing interest due to their theoretical contributions to the study of magnetism, as well as their applications as new magnetic and magnetooptical high density recording media [1], as magnetic fluids [2], as in the treatment of cancer [3], etc.
