Abstract

Measurement of temperature dependent optical conductivities and dc resistivity of c-axis oriented superconducting MgB₂ films was presented. Drude model with a temperature independent Drude plasma frequency could be used to describe the normal state ab-plane optical conductivities. Bloch-Grüneisen formula with an electron-phonon coupling constant was used to fit the normal state resistivity. MgB₂ was suggested to be a multigap superconductor after analyzing the optical conductivity spectra below critical temperature (T_c) of these films.
