title: From antiferromagnetic order to static magnetic stripes: the phase diagram of (La,Eu)2-xSrxCuO4
abstract: The magnetic order of (La,Eu)2-xSrxCuO4 ( x</=0.2) has been investigated with &mgr;SR techniques. In this system a low temperature tetragonal (LTT) structure is present in the entire range of doping and it is possible to follow the evolution from the long range antiferromagnetic state at x = 0 to the static magnetic stripes. We find a nonmonotonic change of the Neel temperature with increasing x and the obtained magnetic phase diagram of the LTT phase resembles the generic phase diagram of the cuprates where the superconductivity is replaced by a second antiferromagnetic phase.
