Nanomagnetic materials: A review

T.K.S.P.Gupta and S.S.Verma
Sant Longowal Institute of Engineering and Technology, IN

Keywords: Nanomagnets, nanostructures, nanotechnology

Abstract:
Nanotechnology and nanostructured materials have the potential to significantly impact energy efficiency, storage, and production. Such applications can be used to monitor and remediate environmental problems; curb emissions from a wide range of sources; and develop new, "green" processing technologies that minimize the generation of undesirable by-product effluents. As well as being an excellent experimental means of studying fundamental magnetic phenomena, these low dimensionality magnets may in the future form the basis of technologies (information storage, permanent magnets, color printers, etc.). Highlighted areas include the quest for magneto-electronics and the importance of novel interfacial magnetic coupling phenomena. Nanomagnetism includes the artificial structuring of magnetic materials on a sub micron level and natural occurring magnetic entities such as molecules and clusters. Here the emphasis will be on the macroscopic behaviors found in single domains of quantum spins, quantum coherence, dissipation and tunneling of magnetization, and disorder and frustration effects. Nanometer-sized magnetic particles are situated at the frontier between classical and quantum magnetism.
