| Summary: | 碩士 === 國立交通大學 === 電子物理系所 === 94 === The electromagnetic properties of La0.7Ca0.3MnO3 (LCMO) thin films at THz frequencies have been studied by Terahertz-Time Domain Spectroscopy (THz-TDS). The THz electric fields transmitted through the LCMO thin films at various temperatures were measured. The temperature and frequency dependence of the complex index of refraction, dielectric function and conductivity can be determined from the complex transmittance and Fresnel equation. In addition, we carefully analyzed the data of dielectric constant spectra of LCMO thin films by a simple Drude model including the plasma frequency and the scattering rate as parameters.
