 note = {Faraday rotation and ellipticity were measured at room temperature in the photon energy range of 1.5-4.2 eV on Y3-xPrxFe5O12 (x = 0-2.0) epitaxial films grown by rf sputtering. The Pr3+ substitution induced negative rotation and ellipticity which satisfy a paramagnetic dispersion relation caused by an electronic transition centered at 3.0 eV. The maximum value of the Pr3+ contribution was -2.5×104deg/cm in rotation and -4.1×104deg/cm in ellipticity for x = 2.0. Optical absorption measurements showed that this is a new transition induced by the coexistence of Pr3+ and Fe3+, and it is neither 4f-5d intra-atomic transition nor 4f-4f transition originating from Pr ions as previously supposed., application/pdf},
