Magneto-elastic coupling in Tb3Ga5O12 garnet
Aiming at shedding light on the intriguing phonon Hall effect recently reported in Tb3Ga5O12, we wish to investigate the CEF and phonon spectrum in this particular material in an applied magnetic field. Previous measurements provide evidence for hybrid magneto-elastic modes, mixing CEF lines and transverse acoustic phonons. We plan to determine how this coupling evolves in a field and thus contribute to a better understanding of the magneto-elastic coupling and in turn of the phonon Hall effect.
