Stress-Induced Angular Momentum Quenching in MgO:Fe2+as Observed by Mössbauer Spectroscopy
1970
Physical Review B
Preserved Fulltext
Under the influence of a suitable uniaxial stress, the quenching of the electronic angular momentum of the low-lying threefold degenerate rs o level of Fe 2 + in cubic MgO has been observed by Mossbauer spectroscopy. The result is consistent with Ham's model for the appearance of a quadrupole doublet at low temperatures. A value for the strain coefficient of Fe 2 + in MgO has been obtained: Gn = 585 em-I. z -2", 2", an "2, respectIve y.
