Abstract
Till only a few years ago, all known materials showing spontaneous magnetisation at finite temperature were continuous lattice compounds, that is, their crystal structures contained no identifiable molecular units of the kind that would survive dissolution in a solvent or evaporation into the gas phase. But are the basic mechanisms of moment alignment different, or the resulting macroscopic properties of this novel class of molecular-based magnets notably different from the ones that have become familiar to physics over the last 150 years? The answer is yes, but only partly. As a contribution to the coming of age of molecular magnetism, this chapter discusses features which only molecular-based lattices are able to present. Examples come from our own work on hybrid lattices combining continuous and molecular ingredients, and systems where only Van der Waals interactions mediate the exchange. Dimensionality, chirality, mesomorphism, transparency and processibility are some properties invoked.
