Review on Recent Progress in Magnetic Nanoparticles

Ball milling is a top-down approach of producing MNPs from the bulk material. It is a simple and convenient process which involves the mechanical grinding of coarse-textured particles into fine-textured particles (Fecht et al., 1990; El-Eskandarany, 2001). This method was first developed in 1970 (Benjamin, 1970). The working principle is very
