The magnetic phase diagram of (La 1-xBax)2CUO4 has been established by 139La nuclear quadrupoIe resonance and the specific heat measurements. The magnetic order changes at x=0.008 from a three dimensional antiferromagnetic (AF) type to an incoherent one due to a short-range coupling among the successive planes and continues to x=0.025 where the superconductivity appears. Since the average staggered moments are found to be almost constant between x=0.0 and 0.01, the static AF-coherence over long distance within the CuO2 planes is demonstrated to survive even in the incoherent ordered state. The phase diagram is considered to be within the same scheme as that proposed by Aharony et al.
