Thermodynamic properties of the S= 1/2 Heisenberg chain in transverse staggered magnetic field Hys and uniform magnetic field Hx perpendicular to the staggered field is studied by the finite-temperature density-matrix renormalization-group method. The uniform and staggered magnetizations and specific heat are calculated from zero temperature to high temperatures up to T = 4J under various strength of magnetic fields Hys and Hx. The specific heat and magnetization of the effective Hamiltonian of the Yb4As3 are also presented, and field induced gap formation and diverging magnetic susceptibility at low temperature are shown.
