The subject deals with the basic magnetic arrangement in solids. In the second part, it solves interactions in magnetic materials, the formation of a domain arrangement and the problem of hysteresis. The last part is an introduction to nanomaterials magnetism.
1) ORIGIN OF THE MAGNETISM IN MATERIALS – GENERAL DESCRIPTION
Magnetic moment – origin
2) BASIC MAGNETIC ARRANGEMENT – OVERVIEW
Diamagnetism, paramagnetism, ferromagnetism, antiferromagnetism and ferrimagnetism
3) BASIC MAGNETIC ARRANGEMENT – DESCRIPTION
Classical resp. semi-quantum theory of diamagnetism, paramagnetism, ferromagnetism, antiferromagnetism and ferrimagnetism
4) INTERACTIONS IN MAGNETIC MATERIALS
Origin, exchange interactions, magnetostatic energy, magnetic anisotropy, magnetoelastic energy and magnetostriction
5) MAGNETIC DOMAINS
Single and multidimensional particles, domain walls, critical parameters, wall movement
6) MAGNETIC HYSTERESIS
Hysteresis loop, parameters, influences
7) MAGNETISM OF NANOMATERIALS
Single-domain particles, Stoner-Wohlfarth model, superparamagnetism, spin bending, interparticle interactions, collective magnetic excitations, surface effects of magnetic nanoparticle, thin films and multilayers
