Abstract

We have measured the resistivity ρ(T) in high quality Hg_0.9Tl_0.1Ba₂Ca₂Cu₃O _8+δ thin films and specific heat in Hg_0.9Tl_0.1Ba₂Ca₂Cu₃O _8+δ polycrystals samples. The resistivities ρ_ab(T) in the thin film samples show systematic deviation from T-linear behavior below a temperature T_D well above T_c. The magnitude of the specific heat jump δγ(T_c) decreases sharply with little change in T_c or in γ(T) well below or well above T_c. Those behaviors reflect the opening of the spin gap.
