Spin glass behavior in the Dy3-xYxTaO7 (0≤x≤1) system

Weberite-type crystal structure of the Dy3−xYxTaO7 compounds. In this structure the magnetic sublattice is formed by Dy3+ cations in an arrangement of distorted tetrahedra at the second-nearest neighbor site; this arrangement suggests geometric frustration that leads to a spin glass behavior
