Spin dynamics in La2-xSrxCuO4 doped with Fe: An ESR study (in English)
Abstract
The electron-spin resonance (ESR) of La2-xSrxCu1-yFeyO4 is investigated on polycrystalline samples for 0 <= x <= 0.3 and 0 <= y <= 0.1. The ESR spectrum consists of the superposition of two Lorentzian lines, which can be unambiguously attributed to Fe3+ and intrinsic Cu-spin polaron signals. The simultaneous observation of both signals allows to describe the temperature dependence of the relaxation of the Fe3+ ions in terms of Cu-spin fluctuations.
