A detailed presentation of the physics of the various hysteresis models
that are currently used to explain the magnetization reversal process,
including coherent and incoherent magnetization processes,
micromagnetism and its application in thin films, multilayers,
nanowires, particles and bulk magnets, domain wall pinning and domain
wall dynamics, and Preisach modelling. Some of the faulty concepts and
interpretations that still exist in the literature are rectified.
Magnetic imaging techniques are reviewed, including TEM, SEM, magnetic
force microscopy, and optical microscopy. Temperature, field and angular
dependence of coercivity, magnetic interactions and magnetic phenomena
are reviewed and their effect on magnetic hysteresis is discussed. The
magnetic properties of novel materials are discussed, including
nanoparticles, nanocrystalline granular solids, particulate media, thin
films, and bulk magnets. Finally, present and future applications of
novel materials are presented, including magnetic and magneto-optic
recording media, magneto-electronics, sensors, magnetic circuit design,
and novel structures created from rigid, high-energy permanent magnets.
