| dc.description | Recent magneto-optical investigations of exotic rare-earth compounds, such as reduced-moment magnets and magnetic superconductors, are critically reviewed. Representatives of the first class are cerium compounds like CeSb and CeRh<sub>3</sub>B<sub>2</sub>. The former material has attracted particular theoretical attention due to its record Kerr rotation of 14°. CeRh<sub>3</sub>B<sub>2</sub> raised the question, whether a Curie temperature of 115 K can originate from reduced Ce moments. A line shape analysis of the magneto-optical spectra shows that Ce, indeed, is responsible for the moment in CeRh<sub>3</sub>B<sub>2</sub> and it allows to specify the nature of its ground state.Representatives of the second class are Chevrel phases containing Eu<sup>2+</sup> ions. The characteristic magneto-optical spectrum of this ion has been identified in various Eu<sub>1-x</sub>Pb<sub>x</sub>Mo<sub>6</sub>S<sub>8</sub> and Eu<sub>1-x</sub>Sn<sub>x</sub>Mo<sub>6</sub>S<sub>8-y</sub> Se<sub>y</sub> Chevrel phases. The temperature and field dependence of the Kerr rotation allow a study of the evolution of the spin polarization of the 4f<sup>7</sup> state in the normal, superconducting and field-induced superconducting state. |
