A 1∕2 magnetization plateau in magnetic fields above 23 T and antiferromagnetic (AF) long-range order (AFLRO) in low fields were found in Cu2CdB2O6. Experimental results agree with quantum Monte Carlo results for an expected spin system. There are two kinds of Cu sites, [Cu(1) and Cu(2)], which are located adjacent to each other. Unexpectedly, spins on the Cu(1) and Cu(2) sites are in a nearly spin-singlet state and form AFLRO, respectively, although interactions between the Cu(1) and Cu(2) spins cannot be ignored. Cu2CdB2O6 is the first material which shows such coexistence in an atomic scale.
