|Abstract:||Magnetic refrigeration is a good alternative to gas compression technology due to higher efficiency and environmental concerns. Magnetocaloric materials must exhibit large adiabatic temperature variations and a large entropic effect. MnAs shows the colossal magnetocaloric effect under high pressures or with Fe doping. In this work the authors introduce a class of materials- Mn1-x Cux As -revealing a peak colossal effect of -175 J (K kg) for a 5 T field variation at 318 K and ambient pressure. © 2007 American Institute of Physics.|
