Revisiting optical properties of MgB2 with a high-quality sample prepared by a HPCVD method
Abstract We investigated a high-quality MgB2 thin film with a thickness of ~1000 nm on an Al2O3 substrate using optical spectroscopy. We measured the reflectance spectra of the film at various temperatures both below, and above, the superconducting transition temperature, T c $$\simeq $$ ≃ 40 K....
