High-frequency study of the orbital ordering resonance in the strongly correlated heavy fermion metal CeB6

A recently discovered magnetic resonance in the orbitally ordered phase of CeB 6 (orbital ordering resonance) is studied in a wide frequency range v = 44–360 GHz. The g -factor for this resonance was found to increase with frequency from g ( v = 44 GHz) ∼ 1.55 to g ( v > 250 GHz) ∼ 1.7. In additi...

Zusammenfassung:A recently discovered magnetic resonance in the orbitally ordered phase of CeB 6 (orbital ordering resonance) is studied in a wide frequency range v = 44–360 GHz. The g -factor for this resonance was found to increase with frequency from g ( v = 44 GHz) ∼ 1.55 to g ( v > 250 GHz) ∼ 1.7. In addition to the orbital ordering resonance, a new magnetic resonance with a g -factor of 1.2–1.3 was detected for frequencies exceeding 200 GHz.
