摘要：

The magnetic properties of Gd2CuO4 have been investigated by magnetization, electron paramagnetic resonance (EPR) and neutron-diffraction measurements in the temperature range 1.5-50 K to determine the magnetic phase diagram and to search for the origin of the weak ferromagnetism which has been observed in this compound. Gd2CuO4 is found to have a rather complex magnetic phase diagram consisting of at least four distinct magnetic phases. The nature of the weak ferromagnetism is discussed and a possible origin of both the weak ferromagnetism and the phase transitions is proposed.
