SUMMARY

The discussion centers on the effects of external magnetic fields on spin systems and their thermal interactions with lattice systems, specifically in the context of adiabatic demagnetization refrigeration (ADR). Participants confirm that the primary focus is indeed on ADR, exploring how external magnetic fields influence the temperature and heat capacity of these systems. The conversation emphasizes the importance of understanding the dynamics between spin orientations and lattice interactions under varying magnetic conditions.

The degrees of freedom associated with the possible orientations of the spins of the magnetic atoms constitute a spin system, which is in thermal interaction with the degrees of freedom of translational motion of all the atoms which constitute the lattice system.

If the external magnetic field acts on the spin system alone, what happens when the field is NOT changed too rapidly to the lattice and spin systems and temperature and total heat capacity?

Are you simply referring to adiabatic demagnetization refrigeration (ADR)?
Or to something else?
 
yes, ADR.
 
Any ideas?
