Crystal electric field level scheme leading to giant magnetocaloric effect for hydrogen liquefaction
In recent years, magnetic refrigeration has attracted considerable attention for hydrogen liquefaction. Most materials used for magnetic refrigeration contain heavy rare earth ions with complex crystalline electric field energy splittings, whose effect on the magnetic entropy change Δ S M has not be...

| description | In recent years, magnetic refrigeration has attracted considerable attention for hydrogen liquefaction. Most materials used for magnetic refrigeration contain heavy rare earth ions with complex crystalline electric field energy splittings, whose effect on the magnetic entropy change Δ

has not been systematically studied. In particular, the theoretical upper limits of ∣Δ
S

∣ for general heavy earth cases are unknown. Here, we show that the crystalline electric field level schemes result in a large Δ

for general heavy rare earth cases. We provide a specific example of the magnetic refrigeration material HoB

using inelastic neutron scattering experiments combined with mean-field calculations with crystal field splitting and exchange interactions. The relationship between Δ
S
M
and crystal field parameters presented in this study can be useful for developing compounds with a large ∣Δ

Magnetic refrigeration materials containing rare-earth ions are promising for hydrogen liquefaction and energy storage applications. Here, the role of crystal-field level splitting on magnetic entropy change is systematically investigated, comparing mean-field calculations with neutron scattering experiments in HoB
