Abstract
The angular dependence of the in-plane transverse magnetization of an untwinned single crystal of LuBa2Cu3O7-delta has been studied in the M eissner state as a function of temperature and magnetic field. The amp litude of the Fourier component of the signal with angular period pi/2 has been found to be smaller than the theoretical prediction for a d- wave pairing state. The results are consistent with isotropic pairing, but they do not rule out nodeless anisotropic pairing states.
