These topics are: the magnetopause (topology and microscopic theories of structure, dynamical effects due to interplanetary magnetic fields and solar-wind pressure changes), the plasmasphere (topology, theories of origin, time variations, plasmaphysical processes), the proton radiation belt (origin, theory of particle motion in the geomagnetic field using invariants), wave-particle interaction (simplified theory, experimental verification), the electron radiation belt (origin, transport, losses), excitation of waves (velocity space instabilities, applications and experimental verification), aurorae (origin, plasmaphysical effects associated with barium cloud releases in the ionosphere), the plasmamantle and the plasmasheet (topology, possible connection between the two phenomena), and finally a brief overview of magnetospheres in the Solar System which have been accessible to 'in situ' investigation using space probes.

After a general introduction, two sections are devoted to a survey of the theories of spin temperature and of nuclear relaxation in solids. This is followed by a short section on the so-called well-resolved solid effect, and a much more detailed one on DNP by thermal mixing in the non-linear low spin-temperature domain. One then analyses the various methods of measurement of the nuclear polarisation, as well as an indirect method of detecting the electronic resonance based on the existence of large nuclear polarisations. The final section describes briefly several applications of dynamic nuclear polarisation.
