Fig. 6: Practical low-temperature cooling performances of Gd2B2MoO9.
From: Refrigeration down to 0.16 K using a frustrated magnet Gd2B2MoO9

Direct measured the adiabatic demagnetization cooling T(μ0H) curves highlights a refrigeration down to 0.16 K, surpassing the commercial Gd3Ga5O12 refrigerant. Inset presents temperature dependence of adiabatic temperature change ΔTad(T) curves by indirect calculation (dashed lines) and by direct measurement (marked by stars).
