摘要：

We present here the results of an investigation into the electron spin resonance in single crystals of La1-xSrxMnO3 with x = 0.1, 0.2, 0.3. It turns out that the linewidth (Delta H) and the intensity (I) can be expressed as Delta H = Delta H(theta) + b(T - theta) and I(T) proportional to (T - theta)(-1), respectively, where theta is the appropriate Curie-Weiss constant. Various models are discussed. (C) 1997 Elsevier Science B.V.
