Dysprosium stannate (Dy<sub>2</sub>Sn<sub>2</sub>O<sub>7</sub>) is an inorganic compound, a ceramic of the stannate family, with pyrochlore structure.
Dysprosium stannate, like dysprosium titanate and holmium stannate, is a spin ice material. In 2009, quasiparticles resembling magnetic monopoles were observed at low temperature and high magnetic field.
