Dysprosium titanate ( Dy 2 Ti 2 O 7 ) is an inorganic compound , a ceramic of the titanate family, with pyrochlore structure.

Dysprosium titanate, like holmium titanate and holmium stannate , is a spin ice material. In 2009, quasiparticles resembling magnetic monopoles were observed at low temperature and high magnetic field. [2] [3]

Dysprosium titanate ( Dy 2 Ti O 5 ) is used since 1995 as material for control rods of commercial nuclear reactor . [4]
