Frustrated magnetism in fluoride and chalcogenide pyrochlore lattice materials
Dalmau Reig-i-Plessis, Alannah M. Hallas
Abstract
The pyrochlore lattice is the arrangement of corner sharing tetrahedra, the well-known host of a wide range of exotic phenomena driven by magnetic frustration. Until recently, much of the work in this domain was confined to the oxide pyrochlore family of materials. Recent advancements are bringing the same research focus to several new families of materials where halide or chalcogenide anions replace oxygen. Each of these new families opens up new avenues of research such as allowing new magnetic ions, modifications to the local spin anisotropies, and a re-organization of the magnetic energy scales. In this research update, the authors highlight how these effects have opened new pathways for frustrated magnetism research, with an emphasis on future prospects.
