WebSpin ices show low-temperature properties, residual entropy in particular, closely related to those of common crystalline water ice. [1] The most prominent compounds with such properties are dysprosium titanate (Dy 2 Ti 2 O 7) and holmium titanate (Ho 2 Ti 2 O 7 ). Spin ices are geometrically frustrated magnetic systems. While frustration is usually associated with triangular or tetrahedral arrangements of magnetic moments coupled via antiferromagnetic exchange interactions, as in Anderson's Ising model, spin ices are frustrated ferromagnets. It is the very strong local magnetic anisotropy from the crystal field forcing the magnetic moments to point either in or out of a tetrahedron that renders ferromagnetic interactions frustrated in spin ic…
