AI Article Synopsis
- - Neutron diffraction experiments have confirmed the antiferromagnetic structure of Yb₃Ga₅O₁₂ below the transition temperature of 54 mK.
- - The magnetic propagation vector found is k=(1/2,1/2,0), which is unusual for garnet structures.
- - The study suggests that the complex magnetic arrangement involves strong dipolar interactions and hints at significant quantum fluctuations in this spin-1/2 geometrically frustrated magnet.
Article Abstract
The antiferromagnetic structure of Yb_{3}Ga_{5}O_{12} is identified by neutron diffraction experiments below the previously known transition at T_{λ}=54 mK. The magnetic propagation vector is found to be k=(1/2,1/2,0), an unusual wave vector in the garnet structure. The associated complex magnetic structure highlights the role of exchange interactions in a nearly isotropic system dominated by dipolar interactions and finds echoes with exotic structures theoretically proposed. Reduced values of the ordered moments may indicate significant quantum fluctuations in this effective spin-1/2 geometrically frustrated magnet.
