Abstract
Terahertz (THz) radiation with its spectrum extending up to 1 THz has been observed by an illumination of femtosecond optical pulses to optical switch ing devices fabricated on magnetoresistive manganite thin films; Pr0.7Ca0.3 MnO3. The THz radiation strongly depends on temperature T and its T trend r everses sign across charge-orbital and spin-ordering T. (C) 2001 American I nstitute of Physics.
