Magnetic Nanocomposite

Edit

Magnetic nanocomposites are multiphase solids in which magnetic nanoparticles, typically iron oxides, ferrites or metals, are dispersed in a continuous non-magnetic matrix of a polymer, silica or carbon [1]. Magnetic behaviour originates from the particle phase, while mechanical integrity and processability come from the matrix, and the two are coupled through the interfacial region [2]. The composite is superparamagnetic when the embedded particles remain single-domain and below the blocking volume, and ferrimagnetic or ferromagnetic when they are larger or exchange-coupled [3]. This distinguishes them from magnetic alloys, in which the magnetic phase and the structural phase are the same solid [1].
