The torque curves of a detwinned YBa₂Cu₃O₇ single crystal are reversible under μ₀H = 0.8 T and T = 90 K for the three different rotation axes. The effective mass model of the torque gives the anisotropy parameters as γ_ca = √/m_c/m_a = 7.55 ± 0.63 and γ_cb = √/m_c/m_b = 8.95 ± 0.76. The a-b anisotropy parameter can be obtained as γ_ab = √m_a/m_b = γ_cb/γ_ca = 1.18 ± 0.14. The torque curve in the a-b-plane contains four-fold symmetry.
