Crystal structure and magnetism in rare-earth langasite: (a) the distorted Kagome lattice of the rare-earth ions in R3Ga5SiO14; about 1.5% of the rare-earth sites (orange) are occupied by the holmium ions; the unit cell is shown by thin solid lines; (b) experimental and theoretical magnetization curves of HoxLa3−xGa5SiO14 (x = 0.043) in external magnetic fields parallel to three crystallographic axes and at T = 5 K. Symbols - experiment, solid lines - model accounting for a ground Ho3+ quasidoublet and a Van-Vleck contribution of excited crystal-field states. The inset shows the local magnetic moments of Ho-ions in the saturation regime. Image credit: Weymann et al, doi: 10.1038/s41535-020-00263-9.
