NMR measurements on 121Sb have been performed to clarify the magnetic properties of an anomalous phase transition around 5 K in YbSb. The external magnetic field dependence of the NMR linewidth was measured above and below the transition temperature. The additional broadening of the NMR spectrum at the extrapolated magnetic field of 0 T in the ordered state indicates the presence of an antiferromagnetic order of an extremely reduced moment. The magnetic phase diagram of YbSb was obtained from the temperature dependence of the magnetization under various magnetic fields.
