Magneto-optical investigations of URhAl intermetallic compound

The uranium ternary intermetallic compound URhAl was investigated by means of magneto-optical Kerr effect. Comparative studies of UTX complexes support the conclusion that the magneto-optical spectrum originates mostly from uranium electronic states, the contribution of other metal states being less important. The most prominent peak revealed in the infrared region of the magneto-optical spectra was attributed to the transitions from the ground 5f states to higher d states of uranium.
