Fig. 4: Conventional adiabatic demagnetization refrigeration (ADR) refrigeration circulation.
From: Quantum spin liquid candidate as superior refrigerant in cascade demagnetization cooling
The one-shot adiabatic demagnetization refrigeration follows the A–B–C–D loop consisted of two adiabatic processes (B → C and D → A) and two isothermal processes (A → B and C → D). In the plot, the entropy curves of the paramagnetic salt are computed based on Eq. (2) with the Ce2Mg3(NO3)12 ⋅ 24H2O parameters.
