Abstract :
We have reported on terahertz magnonics, which is a signal transmission with high-energy spin waves (electromagnons) excited by THz wave. As source and medium for electromagnons, we choose Sm3Fe5O12 ultrathin films whose magnetic properties are modified by applying an epitaxial strain. Electromagnons are successfully detected in the strained Sm3Fe5O12 ultrathin film, using a transmittance THz time-domain spectroscopy.
