Rhombic Symmetry

The paramagnetic resonance spectra of five nickel Tutton salts have been analyzed at 290° K. The positions and intensities of the absorption lines are adequately explained by a crystalline electric field of rhombic symmetry. The triplet ground state is resolved into three singlets with an overall splitting of the order of 3 cm -1 , and the spectroscopic splitting factor g is found to be 2.25 ± 0.05. A comparison is made between the directly measured values of the magnetic anisotropy, and the values calculated using the resonance results.

Rare Earth Series

The theory that has been developed for rare-earth ions in crystals is here applied to the double nitrates. The paramagnetic resonance data and certain spectroscopic properties of the different rare-earth double nitrates, depending as they do on the crystalline electric field at a rare-earth ion, are related to the six parameters through which the field is defined. It is found that most of the experimental results can be fitted to values of the parameters that vary in a systematic fashion along the rare-earth series.

Rare Earth Intermetallic

The temperature dependence of the second-order crystalline electric field (CEF) parameters of rare earth intermetallic compound CeZn 2 was deduced from the least-squares nonlinear fit to the reciprocal paramagnetic susceptibility along principal crystalline axes. The results of the calculation are in good agreement with the experimental values.
