摘要
It has been observed that the superconducting properties of the La2CuO4+x (x less than or equal to 0.04) system depend substantially on how the excess oxygen is distributed in the sample: uniformly or in a manner which results in the formation of a new phase. Precise measurements of the magnetic susceptibility of oxygenated La2CuO4+x crystals, combined with data found previously, lead to a revision of the phase diagram of this system.
