摘要：

Electron-Paramagnetic-Resonance (EPR) measurements on La2-xSrxCuO4 single crystals provide experimental evidence of a three-spin polaron of two Cu2+ ions and one p hole. The symmetry properties and the peculiar temperature dependence of the g-value of the EPR line indicate the presence of a dynamical Jahn-Teller distortion (Q(2)-mode) and formation of a collective mode of polarons and surrounding strongly correlated Cu ions (bottleneck regime).
