The magnetocaloric effect (MCE) is a standard technique in cryogenics,
which is useful to cool down from a few Kelvin. All magnetic materials show the
MCE, although the intensity of the effect depends on the properties of each material.
Molecular magnetic coolers are privileged candidates, chiefly because (i) their
quantum characteristics can be controlled and optimised, and (ii) they often are
soluble in common organic solvents, hence allowing the transfer of their functionality.
What used to be an unexplored and emerging research field has entered into adulthood
during the last few years. In fact, more and more molecule-based materials are
being proposed as magnetic refrigerants. In my talk, I will review this research field,
while focusing on the lanthanide acetate tetrahydrate, which has proven to be an
excellent and very versatile magnetic refrigerant for cryogenics.
