Electromagnon in the Z-type hexaferrite (BaxSr1-x)3Co2Fe24O41
Original language description
We studied experimentally the high-temperature magnetoelectric (BaxSr1-x)3Co2Fe24O41 prepared as ceramics a single crystal using inelastic neutron scattering. THz time-domain, Raman, and far-infrared spectroscopies. We observed an electromagnon active in EwIIz polarized spectra. On heating from 7 to 250 K, the frequency of this electromagnon drops from 36 to 25 cm-1 and its damping gradually increases. Applying external magnetic field has a similar effect on the damping and frequency of the electromagnon, and the mode is no longer observable in the THz spectra above 2 T, as the transverse-conical magnetic strucrure transforms into a collinear one.
