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

Cool magnetic molecules Certain materials are known to heat up or cool down when they are exposed to a changing magnetic field. This is known as the magnetocaloric effect. All magnetic materials exhibit this effect, but in most cases, it is too small to be technologically useful. Recently, however, an international collaboration of researchers from

Molecular fridge can reach millikelvin by Simon Hadlington Scientists have laid the foundations for a high-performance ‘molecular fridge’ capable of reaching temperatures within a few thousandths of a degree of absolute zero with a high degree of efficiency. Such ultracoolers could have applications in areas such as ultra-low temperature physics, where alternative technologies such as
