Efficient Room-Temperature Cooling with Magnets

Magnetic cooling is a highly efficient refrigeration technique with the potential to replace the traditional vapor compression cycle. It is based on the magnetocaloric effect, which is associated with the temperature change of a material when placed in a magnetic field. We present experimental evidence for the origin of the giant entropy...

Latent heat of the first-order magnetic transition of MnFeSio.33P0.66

The latent heat of a magnetoelastic phase transition is used as a measure of the magnetocaloric effect since it is directly proportional to the entropy change. Taking MnFeSi0.33P0.66 as a model magnetocaloric material, density functional theory calculations in addition to the phonon calculations based on the density functional perturbation...
