Spin–orbit coupling in groups of (3$d$, 4$f$, 5$f$) ions by means of the segregation of their orbital moments $\textbf{L}_{\textbf{r}}$ creates new substance—orbital glass. In many-electron operator-spinors’ representation, spin–orbit coupling in sea of band fermions ($f_{\textbf{r}}$ or $h_{\textbf{r}}$) is expressed by their density ($n_{e}$ of electrons or $n_{h}$ of holes). The orbital-glass influence on bond spectra $\varepsilon_{\textbf{k}}(e, h)$ is expressed by segregation-excitation energies. Fractional spin ($\textbf{S}$) and orbital ($\textbf{L}$) moments of 3$d$-elements are determined by spin–orbit coupling. Light 4$f$-elements have orbital moment $L$ < 0 due to electron charges $e_{\textbf{r}}$ < 0, but heavy elements have orbital moment $L$ > 0 due to hole charges $h_{\textbf{r}}$ > 0.
Ключевые слова: spin–orbit coupling, orbital glass.
