Increasing the dimensionality of cryogenic molecular coolers: Gd-based polymers and metal-organic frameworks

The magnetothermal properties of a coordination polymer and a metal-organic framework (MOF) based on Gd3+ ions are reported. An equally large cryogenic magnetocaloric effect (MCE) is found, irrespective of the dimensionality. This combined with their robustness makes them appealing for widespread magnetic refrigeration applications.
