Dy2ScNbO7: a new spin ice candidate?

ORAL

Abstract

Using standard solid state methods, Dy2ScNbO7, a pyrochlore oxide, was synthesized. While the A-site is occupied by the magnetic Dy3+ cation, the B site is split into a mixture of disordered non-magnetic Sc3+ and Nb5+ cations. It appears that Dy2ScNbO7 has a spin ice ground state that is similar to the titanate analogue, Dy2Ti2O7. Despite its similarities, Dy2ScNbO7 exhibits much faster low temperature spin dynamics than any other dysprosium spin ice candidate. Attempts to grow single crystals of Dy2ScNbO7 have been successful using the floating zone image furnace. Recent characterization results will be presented.
