hot and cold sides of the AMR, b The establishment of the temperature prole along the AMR

AMR cycle)
After a certain number of cycles (the number strongly depends on the operating
conditions), a periodic steady state is reached. This happens when the temperature
of the AMR between two successive cycles does not change (in this case decrease)
anymore. The entire response of the magnetocaloric material at the hot and cold
