Abstract
By means of Ni-61 Mossbauer measurements, the hyperfine magnetic field H-hf of Ni-61(2+) ions in the compressed (c/a < 1) tetrahedral sites of the spinel chromite Cu0.9Ni0.1Cr2O4 was found to be 800 kOe, which is the largest ever reported for Ni-61. The large H-hf can be elucidat ed on the basis of the orbital angular momentum in the degenerate grou nd state of Ni2+ ions.
