Rare-earth tuning of magnetic entropy and interaction scales in K${}_3$$Ln$(PO${}_4$)${}_2$ ($Ln$ = Yb, Gd) for adiabatic demagnetization refrigeration

Yonglin Wang, Chuandi Zhang, Jianglong Zhang +8

Adiabatic demagnetization refrigeration (ADR) based on frustrated rare-earth magnets provides a promising route toward helium-free sub-Kelvin cooling, while balancing magnetic entr…
