(figure represented) Chilling out: The first 3d/4f cluster based on calixarenes (see picture; purple Mn, brown Cd, red O, blue N) has a high magnetic isotropy and a large number of molecular spin states that are populated even at low temperatures, whereas its ferromagnetic limit is approached only at high applied fields. These results enable the complex to be an excellent magnetic refrigerant for low-temperature applications. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
