Spin-Ice and Other Frustrated Magnets on the Pyrochlore Lattice

Abstract

The recent identification of the dysprosium titanate compound $D{y}_{2}T{i}_2{O}_7$ as a ``Spin-Ice'', i.e. the spin analog of regular entropic ice of Pauling, has created considerable excitement. The ability to manipulate spins using magnetic fields gives a unique advantage over regular ice in these systems, and has been used to study the recovery of entropy. Predicted magnetization plateaus have been observed, testing the underlying model consisting of a competition between short ranged super exchange, and long ranged dipolar interactions between spins. I discuss other compounds that are possibly spin ice like: $H{o}_{2}T{i}_2{O}_7$, and the two stannates $H{o}_{2}S{n}_2{O}_7$, $D{y}_{2}S{n}_2{O}_7$.
