Disorder, Geometric Frustration and the Dipolar Interaction in Rare-Earth Magnets
(University of Waterloo, 2010-08-30)This thesis will present research that studies the role of disorder, geometric frustration and the long range dipolar interaction on the collective behaviour of several insulating, rare earth magnets. Experiments were ... -
Interplay of Disorder and Transverse-Field Induced Quantum Fluctuations in the LiHo_xY_{1-x}F_4 Ising Magnetic Material
(University of Waterloo, 2008-08-25)The LiHo_xY_{1-x}F_4 magnetic material in a transverse magnetic field B_x perpendicular to the Ising spin direction has long been used to study tunable quantum phase transitions in pure and random disordered systems. We ... -
Neutral Radicals as Strongly Correlated Materials: Insights from Theory and Experiment
(University of Waterloo, 2014-12-19)Neutral organic radicals have been pursued for conductive and magnetic solid state properties associated with their unpaired electron. Historically, synthetic challenges and design limitations restricted these materials ... -
Precision Low Temperature Calorimetry and Susceptibility of Magnetic Pyrochlores
(University of Waterloo, 2018-09-19)Spin-ice models feature the same statistical disorder as water ice, which is identified as the source of zero-point entropy. Gapped topological excitations with properties of monopoles are associated with the violation of ... -
Specific Heat of the Dilute, Dipolar-Coupled, Ising Magnet LiHo<sub><em>x</em></sub>Y<sub>1-<em>x</em></sub>F<sub>4</sub>
(University of Waterloo, 2006)The system LiHo<sub><em>x</em></sub>Y<sub>1-<em>x</em></sub>F<sub>4</sub> is a nearly perfect example of a dilute, dipolar-coupled Ising magnet and, as such, it is an ideal testing ground for many theories in statistical ... -
Theoretical studies of frustrated magnets with dipolar interactions
(University of Waterloo, 2009-12-18)Several magnetic materials, in the first approximation, can be described by idealised theoretical models, such as classical Ising or Heisenberg spin systems, and, to some extent, such models are able to qualitatively expose ...
