We present reversible magnetization measurements of a c-axis aligned Sr0.9La0.1CuO2 infinite-layer superconductor with T(c)similar or equal to43 K. The magnetization measured as a function of temperature and angle between the c axis and the external magnetic field are analyzed in terms of the Hao-Clem model. Consequently, the critical fields [H-c(0), H-c1(c)(0), and H-c2(c)(0)] and the characteristic lengths [xi(ab)(0) and lambda(ab)(0)] are derived. We introduce a novel technique to describe the angular dependence of magnetization using the Hao-Clem model by employing the effective mass anisotropy. The anisotropy ratio gamma=9.3 and the zero-temperature coherence length along the c axis xi(c)(0)=5.2 Angstrom are obtained by the technique. The coherence length xi(c)(0) is longer than the c-axis lattice parameter c=3.41 Angstrom, which implies three-dimensional coupling between CuO2 planes even at zero temperature.
