Dimensional reduction by geometrical frustration in a cubic antiferromagnet composed of tetrahedral clusters
Dimensionality is a critical factor in determining the properties of solids and is an apparent
built-in character of the crystal structure. However, it can be an emergent and tunable …

Quantum antiferromagnet bluebellite comprising a maple-leaf lattice made of spin- ions
Y Haraguchi, A Matsuo, K Kindo, Z Hiroi - Physical Review B, 2021 - APS
Spin-1/2 maple-leaf lattice antiferromagnets are expected to show interesting phenomena
originating from frustration effects and quantum fluctuations. We report the hydrothermal …
