Magnetic field and temperature dependence of spin wave excitation and manipulation in RFeO3 (R=Nd) are studied with THz time-domain spectroscopy. Our studies reveal that the spin reorientation transition triggered by external magnetic field is strongly anisotropic: magnetic fields along a-axis is much easier to switch the spin alignment than that along c-axis in NdFeO3 crystal.
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...
Intense terahertz magnetic fields are used to control the magnetization state of ferromagnetic cobalt thin film. The dynamics visualized by magneto optic Kerr effect is non-resonant and take place over sub-picosecond time scale. The observed magnetic response is coherently locked to the THz carrier oscillations.
