SUMMARY:Specific heat and magnetization studies of Dy<sub>2</sub>Ti<su
 b>2</sub>O<sub>7</sub>\, R. G. Herb Condensed Matter Seminar\, Jan Kyc
 ia\, University of Waterloo
DESCRIPTION:Dy<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> is a material wi
 th a pyrochlore lattice of corner-sharing tetrahedral. Crystal-field e
 ffects constrain the magnetic moments of the rare-earth ions to point 
 along the axis connecting the centres of the two neighbouring tetrahed
 ra. As a result\, the magnetic moments are highly frustrated and posse
 ss a ground state containing a large residual entropy similar to water
  ice. Because of this similarity to water ice\, the system is called a
  spin ice. Recently a very interesting perspective has been developed 
 in which the thermal excitations in the magnetic spins are viewed as m
 agnetic monopoles. In this talk\, I will review some of the progress i
 n understanding spin ice and the monopole picture. I will discuss my g
 roup's results of specific heat\, ac susceptibility and magnetization 
 measurements.
