Developed at the U. S. Ames National Laboratory, the novel magnetocaloric heat pump utilizes gadolinium as the working medium ...

They found that a weak magnetic field notably enhances low-temperature cooling in topological materials. Their Nature Materials study reports a figure of merit (zT) of 1.7 ± 0.2 at 180 K and 0.7 ...

Current heating and cooling devices are based on vapor-compression ... A magnetocaloric heat pump works by changing the magnetic field applied to a magnetocaloric material while pumping fluid ...
