Magnetic And Magnetotransport Properties Of Nanostructured Magnetic Materials

Abstract

The magnetic and magnetotransport properties of nanostructured magnetic materials were discussed. These materials were formed by magnetic grains, whose size was of the order of few nanometers, embedded in a matrix of a different magnetic phase. The analysis suggested the alteration of the microstructure of the nanocrystalline system by means of proper thermal treatments.403117126Vázquez, M., Hernando, A., (1995) Adv.
