説明:

(abstract)

The relationship between ΔSM and crystal field parameters derived in this study provides new guidelines for searching for compounds with larger magnetocaloric effects near the hydrogen liquefaction temperature. Recent advancements in density functional theory calculations have unlocked the possibility of predicting CEF pa-rameters for rare-earth systems based on the crystal information. A combination of DFT calcu-lations and the relationships between |∆SM| and the CEF parameters derived in this study would accelerate the search for compounds with a large MCE and design more magnetic refrigera-tion materials.
