Invited for the cover of this issue is research led by Magdalena Fitta at the Institute of Nuclear Physics, Krakow, Poland, in collaboration with scientists at the Jagiellonian University, Institute of Metallurgy and Materials Science, and Krakow University of Technology. The cover image shows the temperature dependence of the change in magnetic entropy for a thin film of a Prussian blue analogue at various external magnetic fields.
