Abstract
In La0.8-x BixSr0.2MnO3 films(x=0 ~ 0.3) prepared by a laser deposition technique, Magneto-Circular Dichroism (MCD) spectra between 1.5 to 6 eV and temperature dependence of resistivity were investigated. In the films without Bi, three optical transitions between 3 and 5 eV in MCD spectra are confirmed by the fitting. The Bi-doping makes shift these three transitions to higher energy and induces a new transition which shifts to lower energy by increasing of doping content. These transitions are ascribed to the charge transfer transitions from O2p to Mndγ(eg).
