 note = {application/pdf, Formation of the antiferroquadrupolar (AFQ) ordering in YbSb (NaCl-type structure) was evidenced microscopically with the 121Sb and 123Sb nuclear magnetic resonance (NMR) measurements. We have observed in the NMR linewidth below TQ=5 K the appearance of an additional field-independent contribution that is proportional to the nuclear electric-quadrupole moment. Thus, the field-independent contribution can be addressed not to any long-range magnetic orderings but to a broken symmetry of the charge distribution associated with the AFQ ordering. The AFQ ordering also gives rise to a large anisotropic Knight shift broadening caused by the anisotropy in the transferred hyperfine field and/or magnetic susceptibility. Fluctuations of the Yb 4f moments are also investigated by using the 121,123Sb spin-lattice relaxation rate measurements},
