Outline of Final Research Achievements

We have investigated monopole dynamics in the spin-ice compound Dy2Ti2O7, which is a topological point defect theoretically similar to the Dirac monopole interacting with magnetic Coulomb force. In particular, we have studied two dimensional monopole dynamics by using ac magnetic susceptibility experiments in an ac field perpendicular to dc. We demonstrated that the slowing down of monopole dynamics in a certain field (~0.4 T) and the extreme speeding up under dc field close to the critical point (~0.9 T). We also have investigated Tb2Ti2O7, which bears resemblance to Dy2Ti2O7, and found that it could be a quantum spin ice in the vicinity of a quadrupole order state, tuned by a precise composition ration of Tb/Ti.
