In highly anisotropic cuprate superconductors it is generally accepted that the reversible magnetization vector, , is essentially perpendicular to the superconducting CuO2 layers in a wide range of crystal orientations with respect to the applied magnetic field, . In a recent work (Mosqueira et al. in Phys. Rev. B 84:134504, 2011) it is shown, however, that the dependence of on the orientation in the reversible mixed state of a high-quality Tl-based cuprate presents a notable deviation from this behavior.
