Abstract

HgBa₂CuO_4+δ (Hg1201) samples with 0.03≤δ≤0.4 have been obtained. The magnetization of the powdered Hg1201 samples was determined using a Quantum Design SQUID magnetometer. It was observed that while the magnetization of Hg1201 increased with δ in the underdoped region, the magnetization decreased with δ in the overdoped region. These results suggest an increase of n_s/m* with oxidation in the underdoped region and a decrease in the overdoped region, similar to that reported in underdoped HTSs and overdoped Tl2201 and Tl1201.
