Supercooled spin liquid state in the frustrated pyrochlore Dy 2 Ti 2 O 7

Significance Frustrated magnetic pyrochlore systems, in which there are many possible favored spin configurations, may host a variety of exotic magnetic phases. For example, some models predict that Dy 2 Ti 2 O 7 hosts a fluid of mobile magnetic “monopoles” that interact via a magnetic Coulomb interaction. Here, we introduce a novel measurement technique that realizes periodic boundary conditions, and use it to examine the magnetization transport dynamics of tori of Dy 2 Ti 2 O 7 . We identify multiple phenomena in the dynamics of Dy 2 Ti 2 O 7 that are characteristic of a supercooled magnetic liquid approaching a glass transition. This highly unusual classical spin liquid forms in a structurally ordered crystal and therefore it may constitute the approach to a novel magnetic glass state.
