Gd₂ molecular cooler gets VIP status and back-cover story

By taking advantage of a relatively high magnetic density combined with a dominant ferromagnetism, gadolinium acetate tetrahydrate displays an unprecedentedly large cryogenic magnetocaloric effect. The remarkable temperature drops, reported by M. Evangelisti and co-workers in their Communication (DOI: 10.1002/anie.201102640), suggest that this molecular nanomagnet can be efficiently employed as a magnetic refrigerant for low-temperature applications (picture by O. Roubeau).
