“…Estimations of the developed SN-SIL-IR, SG-SIL-IR, SN-SIL-EC, and SG-SIL-EC models are presented with the corresponding absolute error after comparison with the measured relative cooling power values. The developed SN-SIL-IR model with ionic radii-based descriptors shows excellent performance and predicts the relative cooling power of most of the dysprosium-based magnetocaloric compounds exactly, except for a few compounds with slight deviations, such as Dy 2 Cu 2 Cd [49], Dy 2 Cu 2 Cd [46], DyNiSi [49], DyB 2 [49], Dy 2 Cu 2 Cd [46], DyCoNi [8], DyNiSn [49] and Dy 2 Co 2 Ga [46]. Predictions of other developed models, such as the SG-SIL-IR, SN-SIL-EC, and SG-SIL-EC models, have slight associated deviations from the measured values.…”
