Magnetocaloric and other Properties of Cold Rolled Gd Ribbons

Abstract:

In this work we investigate magnetocaloric effect and heat capacity of Gd cold rolled ribbons. Such materials are easy to produce, they are flexible and convenient for using in magnetic cooling devices. It is shown that the magnetocaloric effect is strongly dependent on thickness of the ribbons. Severely rolled ribbons demonstrate rather a small magnetocaloric effect. However, a special heat treatment procedure makes it possible to enhance the effect up to the value observed in polycrystalline Gd.
