However, when the measured relative Verdet constants of the trivalent rare earth ions are compared to the relative $p^{2}/g$ values, only a very limited correlation is noted. The explanation of this observation lies in the apparent large variation of the other parameters on which the Verdet constant depends, namely, the frequencies of the allowed electric dipole transitions and the respective transition probabilities. Finally, it appears more than fortuitous that there exists an orderly decrease in the ratio of the Verdet constant to $p^{2}/g$ as a function of atomic number going from $Cc^{3+}$ to $Gd^{3+}$ and $Tb^{3+}$ to $Yb^{2+}$.” en_US dc.format.extent 123045 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title COMPARISON OF THE OPTICAL FARADAY ROTATION OF THE-TRIVALENT RARE EARTH IONS en_US dc.type article en_US
