Abstract

We have measured magnetization of grain-aligned Hg_0.7Cr_0.3Sr₂CuO_4+δ high-T_csuperconductors with high magnetic fields perpendicular to the CuO₂ planes. Analyses based on fluctuation magnetization models show that this compound has a highly two-dimensional character, or weak coupling between the CuO₂ planes. This is against the previous belief of stronger flux pinning due to a shorter interlayer distance in this compound than in the pristine HgBa₂CuO_4+δ. The highly two-dimensional character is also confirmed by the good 2D scaling behavior of high-field magnetization around T_c(H).
