Abstract

We investigated temperature (formula presented)- and magnetic field-dependent optical conductivity spectra (formula presented) of a (formula presented) single crystal, showing intriguing phase coexistence at low T. At (formula presented) a dominant charge-ordered phase produces a large optical gap energy of (formula presented) At (formula presented) at least two absorption bands newly emerge below 0.4 eV. Analyses of (formula presented) indicate that the bands should be attributed to a ferromagnetic metallic phase and a charge-disordered phase that coexist with the charge-ordered phase. This optical study clearly shows that (formula presented) is composed of multiphases that might have different lattice strains.
