The magnetic field source is the most expensive element of a magnetic refrigeration device. The design of an efficient magnet with high and low field regions, using reduced volumes of permanent magnets, is of paramount importance for the practical ap

For magnetocaloric materials the total entropy diagram S ( T ) in different magnetic fields is of central importance. From such a plot the isothermal entropy change Δ S T and the adiabatic temperature change Δ T ad can be well-defined. Aim of this
