a The maximum reversible isothermal entropy change ΔSr-max and (b) reversible adiabatic temperature change ΔTr-max for (CH3–(CH2)n−1–NH3)2MnCl4 (n = 10) single crystal and (CH3–(CH2)n−1–NH3)2MnCl4 (n = 9) compared to that of plastic crystals PG ((CH3)C(CH2OH)3), NPG ((CH3)2C(CH2OH)2), NPA ((CH3)3C(CH2OH)), 1-Cl-adamantane (Cl-ada), 1-Br-adamantane (Br-ada), and the spin-crossover material Fe3(bntrz)6(tcnset)6 under variable pressures. The (CH3–(CH2)9–NH3)2MnCl4 reported in ref. 25. is also included. The inset of (a) shows the enlarged details of the comparison of reversible ΔSr-max under P ≤ 0.1 GPa for all samples. Note that the solid lines represent the results of (CH3–(CH2)n−1–NH3)2MnCl4.
