Linear and Nonlinear Optical constants of BiFeO_3

Kavli Affiliate: Darrell Schlom | First 5 Authors: Amit Kumar, R. Rai, Nikolas Podraza, Sava Denev, Mariola Ramirez | Summary: Using spectroscopic ellipsometry, the refractive index and absorption versus wavelength of the ferroelectric antiferromagnet Bismuth Ferrite, BiFeO_3 is reported. The material has a direct band-gap at 442 nm wavelength (2.81 eV). Using optical second harmonic […]
