Emergent Fields, Flat Bands and Phase Competition: A Study in Magnetic Pyrochlore Systems
(University of Waterloo, 2020-09-18)We investigate spins models on the pyrochlore and the breathing pyrochlore lattice. Specifically, we study polarized neutron scattering in classical spin ice modelled via Ising spins with anti-ferromagnetic interactions. ... -
A Study of Order-by-Disorder Phenomenon in Frustrated Magnetic Systems Near Criticality
(University of Waterloo, 2014-04-25)Order-by-disorder is the phenomenon of the selection of a long-ranged ordered state by fluctuations in a many-body system. This mechanism, at first sight, seems paradoxical, since fluctuations (disorder) intuitively tend ... -
Symmetry Breaking, Order-by-Disorder, Fragmentation, and Spin-Liquids in the Magnetic Pyrochlore Lattice with Anisotropic Interactions
(University of Waterloo, 2023-01-26)Within the study of frustrated magnetism, the pyrochlore lattice is deemed a fruitful ground where phenomena such as quantum and thermal order-by-disorder, moment fragmentation, and spin-liquids, both quantum and classical, ... -
Ultra-low temperature dilatometry
(University of Waterloo, 2010-10-28)This thesis presents research of two novel magnetic materials, LiHoF4 and Tb2Ti2O7. Experiments were performed at low temperatures and in an applied magnetic field to study thermal expansion and magnetostriction using a ...
