摘要：

We report results of the study of the recently discovered magnetic resonance in CeB6, which is characteristic to the phase 11 in the magnetic phase diagram of this strongly correlated heavy fermion metal. Experiments were carried out in a wide frequency range omega/2 pi=44-360 GHz in magnetic field up to 30 T. It is found that the previously reported magnetic resonance exists at all frequencies studied and the g-factor for this resonance increases with frequency from g(omega/2 pi=-44 GHz)similar to 1.55 to g(omega/2 pi>250 GHz)similar to 1.7. In addition to the aforementioned mode of magnetic oscillations an additional magnetic resonance with the g-factor 1.2-1.3 is detected for the frequencies exceeding 200 GHz. This effect may be a consequence of a complicated magnetic structure of the phase II, which is not foreseen in the standard models of the low temperature magnetic ordering in CeB6.
