The magnetic penetration depth λ(T) of three HgBa2CuO4+δ samples with 0.16 < δ ≤ 0.27 has been determined from the reversible magnetization. The obtained λ follows a BCS-like correlation of 1/λ2 ∝ 1-(T/Tc)2 over whole measured temperature range in an underdoped sample with Tc ∼ 90 K, but deviates significantly from similar fits in an overdoped sample with the same Tc and an optimum doped sample, whose 1/λ2 's depends on T nearly linearly below Tc/2. This asymmetry between the underdoped and overdoped samples suggests that the T-dependence of 1/λ2 is affected by doping in a complicated way.
