Terahertz (THz) radiation with its spectrum extending up to 1 THz has been observed by an illumination of femtosecond optical pulses to optical switching devices fabricated on magnetoresistive manganite thin films; Pr[sub 0.7]Ca[sub 0.3]MnO[sub 3]. The THz radiation strongly depends on temperature T and its T trend reverses sign across charge-orbital and spin-ordering T. © 2001 American Institute of Physics.
