Low-Energy Excitations in La1.2Sr1.8Mn2O7 Investigated by Ellipsometry

The low-energy excitations of the bilayered manganite La{sub 1.2}Sr{sub 1.8}Mn{sub 2}O{sub 7} have been explored by spectral ellipsometry from two faces of a single crystal over the range from 0.006 to 0.6 eV. This compound is a paramagnetic insulator at ambient temperature, with a transition to a f...
