Spin ice behavior in Dy2Sn2-xSbxO7+x/2 and Dy2NbScO7
arXiv:0707.4009 · doi:10.1103/PhysRevB.76.214413
Abstract
We report the magnetic and thermal properties of Dy2Sn2-xSbxO7+x/2, x = 0, 0.25, and 0.5, and Dy2NbScO7. We find evidence for Ising-like single ion ground states in the Dy2Sn2-xSbxO7+x/2 materials. These materials possess nearly the same zero point entropy as the canonical spin ices Ho2Ti2O7 and Dy2Ti2O7, strongly suggesting that they have spin ice states at low temperatures. We also observe a somewhat reduced zero point entropy in Dy2NbScO7, which is possibly associated with the higher level of cation disorder. The ice-like states in these materials with cation disorder on the B-sites of the pyrochlore lattice provide new evidence for the robust nature of spin ice behavior in the presence of disorder.
