Abstract

Spectral ellipsometry is used to determine the dielectric function of an untwinned crystal of ${\mathrm{L}\mathrm{a}\mathrm{M}\mathrm{n}\mathrm{O}}_{3}$ in the range 0.5--5.6 eV at temperatures $50\ensuremath{\le}T\ensuremath{\le}300\text{ }\text{ }\mathrm{K}$. A pronounced redistribution of spectra...
