|This manuscript is based on series of lectures about Nanomagnetism. Parts have
been given at the European School on Magnetism, at the Ecole Doctorale de Physique
de Grenoble, or in Master lectures at the Cadi Ayyad University in Marrakech.
Nanomagnetism may be dened as the branch of magnetism dealing with lowdimension
systems and/or systems with small dimensions. Such systems may display
behaviors dierent from those in the bulk, pertaining to magnetic ordering, magnetic
domains, magnetization reversal etc. These notes are mainly devoted to these
aspects, with an emphasis on magnetic domains and magnetization reversal.
Spintronics, i.e. the physics linking magnetism and electrical transport such as
magnetoresistance, is only partly and phenomenologically mentioned here. We will
consider those cases where spin-polarized currents in
uence magnetism, however not
when magnetism in
uences the electronic transport.|
