Using the density matrix renormalization group method of the spin 1/2 magnetic behavior of the compound K3Cu3AlO2(SO4)4, which represents the physical realization of the diamond chain, was studied. For the values J1 = J3 = 132K, J2 = 336K of coupling constants we obtained the magnetization plateau in the region 50-300 T of the external magnetic field. We used the ALPS (Algorithms and Libraries for Physics Simulations) library for the numerical calculations.
