Abstract

The dynamic response of La1 - xSrxMnO3 perovskites has been studied in the low doped regime (x≤0.14). The frequency dependence of the ac susceptibility gives clear indications in favor of the existence of electronic phase separation not only in the O″ phase but also at temperatures between the ferromagnetic transition temperature TC, and the O′ - O″ structural transition occurring at TFI. The influence of the Jahn-Teller distortion on the magnetic susceptibility is also detected as a drop in the magnetic susceptibility on crossing down the O - O′ structural transition, while a jump occurs at O′ - O″ transition. A close similarity, both structural and magnetic, between the O and O″ phase is strongly suggested by the experimental results. © 2001 American Institute of Physics.
