Evolution of the Dy3+ magnetic anisotropy in Dy3B2C3O12 garnets
The general magnetic phase diagram calculated for an anisotropic S=1/2 spin on the hyperkagome lattice found in garnets predicts complex magnetic ground states when the magnetic anisotropy departs from the Ising case. We would like to study crystal electric field (CEF) excitations in a series of four dysprosium garnets, in which the A site has been varied to modify the Dy environment. We expect this study to clarify how the Dy3+ Landé g tensor can be tuned with A ; this will lead to the design of dysprosium garnets with unusual and possibly disordered magnetic ground states.
