We report on the enhancement of the terahertz magnetic near-field which is realized by a tapered waveguide. A Tb3Ga5O12 crystal coupled with a double split-ring resonator was pumped by this tightly confined terahertz field, and the magnetic near-field was measured via the magneto-optic sampling. With the use of the tapered waveguide, the amplitude of the magnetic near-field is enhanced by about 2...
Terahertz metamaterial technique enables a sophisticated electromagnetic excitation of materials. Here, we demonstrate resonant excitation of spin precession motion of canted antiferromagnet ErFeO3 using the magnetic near-field produced by split ring resonator (SRR). When the resonance frequency of spin precession was near the magnetic resonance mode of SRR, we observed substantial increase of precession...
