説明
The magnetic-field dependence of optical spectra and their anisotropy have been investigated for a single crystal of ${\mathrm{Pr}}_{1\ensuremath{-}x}{\mathrm{Ca}}_{x}{\mathrm{MnO}}_{3} \phantom{\rule{0ex}{0ex}}(x=0.4)$ at 30 K. The charge-ordered (CO) state is transformed into a ferromagnetic metallic state by a magnetic field of 6.5 T, which is manifested in a huge change of optical spectra over a wide photon-energy region (0.05 eV--3 eV). The observed change in magnitude and anisotropy of the optical spectra with the external magnetic field has been elucidated in terms of the spin- and orbital-ordering structures in the CO state.
