We map the field-temperature (H-T) diagram of the pseudogap state in Bi 2 Sr 2 CaCu 2 O 8+y crystals in a wide range of hole doping. By probing the quasiparticle density-of-states with the c-axis interlayer resistivity measurements in fields up to 60 T we make a systematic evaluation of the pseudogap closing field Hpg that restores the superconductor to its ungapped state. In contrast to the characteristic fields of the superconducting state, Hpg(T) at low temperatures is temperature independent and scales with the pseudogap temperature T* by a simple Zeeman energy scale, indicating a predominant role of spins over the orbital effects in the formation of the pseudogap.

The doping dependence of the bose condensation energy is investigated by using our SU (2) holon-pair boson theory. It is shown that the bose condensation energy U results from the interplay between the charge and spin degrees of freedom and that the doping dependence of U at T=0K is well fit by the relation, [Formula: see text] with Δ0, the spin gap at 0K; x, the hole doping concentration and α, a constant.
