| Abstract: | We report the first measurement of the photo-galvanic circular current antisymmetric tensor component in BaTiO3: Co. The measurement gives a value of this coefficient, for extraordinary beam amplification, of 4×10–9 A/W using a nonstationary measurement technique at a wavelength of 0.632  m.Professor N.
