A method designed to detect magnetic anisotropy $\Delta\chi$ with high sensitivity is improved considerably using microgravity. Oscillation of a magnetically stable axis of a crystal with respect to a magnetic field is observed in the improved method. A fiber that suspends the sample in a horizontal field in conventional methods is omitted using microgravity produced in a drop capsule; in previous methods, the restoration force of the fiber was the standard for measuring $\Delta\chi$. Oscillations of ordinary diamagnetic materials such as apophyllite, calcite, KH2PO4, gypsum, Rochelle salt and urea were achieved at a field intensity of 1.30 T. Biotite and graphite oscillated at 0.0126 T; a small magnetic torque of $4\times 10^{-10}$ N$\cdot$m was detected for the two materials.
