This concise book presents the basic concepts of magnetism and magnetic properties pertinent to permanent magnetic materials. Emphasis is placed on hexaferrite materials for permanent magnet applications, with M-type ferrites as the focal point. The relatively high metallicity of magnetic materials for practical applications imposes limitations for their efficient use. Accordingly, magnetic oxides with ferromagnetic properties emerged as the most widely used magnetic materials for practical applications, owing to their characteristic high resistivity and low eddy current losses, chemical stability, simplicity of production in mass quantities, and other favorable characteristics. An important class of these oxides is the class of hexagonal ferrites developed in the early 1950’s, which dominated the world market of permanent magnet applications since the end of the 1980’s. Among these ferrites, the magnetoplumbite (M-type) hexaferrite, is produced nowadays in large quantities at very competitive low prices, thus providing the permanent magnet market with probably the most cost-effective magnetic material.

Reducing the dimensions of contiguous matter, down to the nanometer scale, confines the electronic and vibrational wavefunctions and results in unique properties which open up a wide vista of potential applications in optics, mechanics, electrical engineering, magnetic devices, catalysis and biomedicine. Nanostructures, characterized by having at least one dimension in the nanometer range, are considered to be a bridge between single molecules and their bulk counterparts. The challenge for nanotechnology is to achieve perfect control of the nanoscale-related properties; which obviously requires correlating the parameters of synthesis with the resultant nanostructures. Nanostructures are also ideal subjects for computer simulation and modeling: in computations related to nanomaterials, one deals with a spatial scaling ranging from a few nanometers to a few micrometers and a time-scaling ranging from a few femto-seconds (fs) to 1 second - with a limit of accuracy better than 1 kcal mol-1.
