摘要：

We present a systematic electron-spin-resonance (ESR) study in single crystals of La1-xSrxMnO3(0 less than or equal to x less than or equal to 0.2). The temperature dependence of the ESR linewidth marks all significant transitions between both orthorhombic (O',O) and the rhombohedral (R) structural phases of the T-x phase diagram. All significant peculiarities of the ESR spectra for low x values within the O' phase can be attributed to the cooperative Jahn-Teller effect on the Mn3+ e(g) states and to the influence of the Dzyaloshinsky-Moriya exchange interaction. Possible relaxation mechanisms at higher doping levels are discussed.
