Abstract
The characteristic features of microwave (30–120 GHz) magnetoabsorption in the magnetic Kondo lattice of CeB6 at liquid-helium temperatures in strong magnetic fields are investigated. It is discovered that the absorption structure is the result of the superposition of the ESR of the cerium 4 f electrons, which has a pronounced doublet structure, and features whose position does not depend on the radiation frequency and which are associated with transitions in the magnetic phase diagram of CeB6. The character of the absorption in the vicinity of the ESR can be linked to the splitting of the 2 F 5/2 state in the crystal field; here the g factor is substantially renormalized from g=2.06±0.03 to g=1.83±0.03 as the temperature decreases from 4.2 K to 1.8 K, respectively.
