Suppression of Pauling's Residual Entropy in Dilute Spin Ice (Dy${}_{1-x}$Y${}_x$)${}_2$Ti${}_2$O${}_7$

S. Scharffe, O. Breunig, V. Cho +4

Around 0.5 K, the entropy of the spin-ice Dy${}_2$Ti${}_2$O${}_7$ has a plateau-like feature close to Pauling's residual entropy derived originally for water ice, but an unambiguous quan…
