The field-swept NMR spectra show asymmetric peak splitting below magnetic phase transition temperature, $T_{\\rm m}$ = 20 K. This splitting is well explained by the occurrence of a magnetic order with propagation vector of $q$ = (2/3, 0, 0) and magnetic moments pointing parallel to the tetragonal [001] axis, offering evidence for uncompensated \"up-up-down\"-type antiferromagnetic ordering with a spontaneous [001] magnetization component.
