| Experimental research on macroscopic phase separation in La2CuO4+δ superconductor and photo-doped cuprates is reviewed. It is shown that the properties of the mixed-phase state strongly depend on the shape and size of the phase domains formed during the phase separation process. The interplay of magnetic and superconducting properties in the mixed-phase state is considered in details. The mechanisms driving the phase separation in La2CuO4 and photo-doped materials are discussed in connection with presented experimental results. |
