Gadolinium displays a strong magnetocaloric effect at temperatures close to room
temperature making it useful in the field of room temperature magnetic refrigeration. We
discuss the importance of including the effects of the demagnetization field when
considering the magnetocaloric properties of gadolinium. The adiabatic temperature change
Δ T ad of gadolinium sheets upon application of a magnetic field has been measured at a
range of applied magnetic fields and sample orientations. A significant dependence of Δ T …
