Abstract
It is shown that there are two paramagnetic complexes for divalent nickel ions in the double‐nitrate crystals. One, which has not been previously described, has a very large‐zero field splitting: D = 2.25±0.10 cm—1 for 1% nickel in La2Zn3 (NO3)12·24H2O at 77°K, and it is shown that this complex is due to ions in the same site as that which produces the more anisotropic cobalt spectrum—the Y‐ion site. The interaction between cerium ions and nickel ions in the other divalent site—the X‐ion site—is shown to be different from the interaction of cerium and cobalt in the same site. The origin of the difference is explained qualitatively.Keywords
