A probe of the radiation field magnetic component based on octahedral Yb3+ in the CaNbGa garnet – CNGG – single crystal

[EN] In a disordered Yb3+-doped CaNbGa garnet – CNGG – single crystal, it is shown that octahedral Yb centers exist up to a solubility limit of about 5 × 1018 cm−3 in addition to the well known dodecahedral Yb which incorporates to a much larger density ∼1021 cm−3. Despite the low density of the oct...
