Electromagnon in the Y-type hexaferrite BaSrCoZnFe11AlO22
Original language description
We investigated static and dynamic magnetoelectric properties of single crystalline BaSrCoZnFe11AlO22, which is a room-temperature multiferroic with Y-type hexaferrite crystal structure. Below 300 K, a purely electric-dipole-active electromagnon at approximate to 1.2 THz with the electric polarization oscillating along the hexagonal axis was observed by THz and Raman spectroscopies. We investigated the behavior of the electromagnon with applied dc magnetic field and linked its properties to static measurements of the magnetic structure. Our analytical calculations determined selection rules for electromagnons activated by the magnetostriction mechanism in various magnetic structures of Y-type hexaferrite.
