In this work we report magnetization and Raman measurements performed in single crystals of Gd2CuO4. The data show the presence of two forbidden Raman modes (fRm), B*1g and B*2g, and weak ferromagnetism (WF) in the CuO2 planes up to temperatures well above TN Cu∼280K. We have studied the T-dependence of the intensity of these fRm and the WF component between 2 and 800K. The WF component and the relative intensity of the two fRm decrease with increasing T and they vanish at T∼650 and 520K, respectively. Recent neutron diffraction experiments observed a tetragonal to orthorhombic phase transition at T≅650K. These results are interpreted in terms of structural distortions within the CuO2 planes that lead to the existence of a distribution of c...
