The magnetic behaviour of La 2- x Sr x CuO 4 was studied using the method of muon spin rotation (μSR). We found that the system orders magnetically for x ⩽ 0.05 and the Nèel-temperatures vary from 250 K for x = 0 to 6 K for x = 0.05. In spite of these drastic changes of the Nèel-temperatures, the extrapolated internal fields at T = 0 K are similar for all samples indicating that the moments at the magnetic (Cu) ions are not changed appreciably. The depolarization rates measured in this experiment are analyzed in terms of an inhomogeneous field distribution in the sample.
