Molecular magnetic coolers: The lanthanide acetate tetrahydrate saga 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. <!--[if gte mso 9]> <w:LsdException Locked="false" Priority="64" SemiHidd
