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 γca = √/mc/ma = 7.55 ± 0.63 and γcb = √/mc/mb = 8.95 ± 0.76. The a-b anisotropy parameter can be obtained as γab = √ma/mb = γcbca = 1.18 ± 0.14. The torque curve in the a-b-plane contains four-fold symmetry.
