Chemical compound
Dysprosium stannate (
Dy2
Sn2
O7) 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.
