Device and method for magnetic refrigeration

A method for magnetic refrigeration, comprising:

• forming a layered structure that includes a sequence of a plurality of magnetocaloric material (MCM) components interlinked with a sequence of a plurality of Peltier modules, wherein each Peltier module of the plurality of Peltier modules is sandwiched between two MCM components of the plurality of MCM components and transfers heat between two adjacently arranged MCM components of the plurality of MCM components, wherein a first layer in the layered structure is a first MCM component in the sequence of the plurality of MCM components and a last layer in the layered structure is a last MCM component in the sequence of the plurality of MCM components, wherein the first MCM component and the last MCM component interact with hot and cold environments to enable transfer of heat between the hot and cold environments;
• concurrently powering each Peltier module in the sequence of the plurality of Peltier modules by using a power source, wherein current in each powered Peltier module flows in a constant direction;
• and
• applying spatially uniform magnetic field to the sequence of the plurality of MCM components, by using a magnetic source.
