We consider the spin-1/2 antiferromagnetic Heisenberg chain in a staggeredmagnetic field describing materials such as copper benzoate and copperpyrimidine dinitrate. Using the density-matrix renormalization group fortransfer matrices (TMRG) we calculate the magnetization of these materials atfinite temperature and arbitrary magnetic field. These results are in excellentagreement with experimental data, allowing for a determination of theinhomogeneity parameter c of copper benzoate (c = 0.043) and copper pyrimidinedinitrate (c= 0.11). The TMRG approach can be applied to rather lowtemperatures yielding singular field and temperature dependences ofsusceptibilities.Comment: 4 pages, 5 figure
