Cooling device and cooling method based on magnetoelectric coupling

摘要

Various embodiments relate to a method (700) for operating a cooling device (300), the method (700) comprising: first changing an electric field (304) in a field region (306), wherein in the field region (306) at least one magnet system magneto-electric coupling is arranged, and thereby heating the at least one magnetic system; and, subsequently, second modifying the electric field (304) in the field region (306) and thereby cooling the at least one magnet system.
