We report the temperature and magnetic field dependence of transport properties in epitaxial films of the manganite La$_{1-x}$Ca$_{x}$MnO$_{3}$ in the overdoped region of the phase diagram for $x > 0.5$, where a charge--ordered (CO) and an antiferrom

We have measured low-temperature terahertz and infrared spectra of La1–xCa xMnO3 with x = 0.5; 0.6; 2/3, 0.7; 3/4, 0.85; 0.9; 0.95; 0.98 and x = 1 in the form of ceramics and epitaxial films. In the charge-ordered state for commensurate dopings (x

Terahertz and infrared spectra of dielectric permittivity and optical conductivity of overdoped manganites La1−xCaxMnO3 (0.5≤x≤1) have been measured at frequencies ν from 4 cm−1 to 700 cm−1 and at temperatures T from 5 K to 300 K. The samp

In the charge-ordered phase of strongly doped manganites La${}_{1\ensuremath{-}x}$Ca${}_{x}$MnO${}_{3}$ ($x\ensuremath{\ge}0.5$) absorption lines appear in the terahertz spectral range for commensurate $x$ values right below the charge-ordering tempe

After the phase transition occurs in manganites La1-xCaxMnO3 (x ≥ 0.5) into a dielectric phase with charge order, right below the corresponding temperature of TCO = 240 K a series of absorption lines appear in the terahertz spectral range, only in
