Abstract
Some basic concepts in magnetism are discussed in the context of molecular solids. A brief outline about the experimental techniques useful to investigate these new magnetic materials is given, with special emphasis in the a.c. susceptibility technique. The basic idea that bulk magnetism can only be achieved by means of inter-molecular magnetic interactions is outlined after explaining the thermodynamic fundamentals of magnetic ordering. Some extension is devoted to account for the phenomena associated with superparamagnetism, since very high spin molecules may exhibit these magnetic properties in the absence of inter-molecular interactions. Finally, some fundamental properties of ferromagnetic materials are commented on discussing how they might affect to molecular ferromagnets.
