The front cover shows droplets of a molecular material for enhanced magnetic refrigeration, i.e., gadolinium acetate tetrahydrate, deposited on a cold silicon substrate. Using quantitative magnetic force microscopy at liquid-helium temperatures, Marco Evangelisti and co-workers demonstrate on page 2984 that the molecules hold intact their magnetic identity after the deposition. This result paves the way towards onchip cryogenic micro-refrigerators. Artwork by O. Roubeau, G. Lorusso, and M. Evangelisti.
