The g-factors of the rotational states along the positive parity yrast band in even-even nuclei 84Zr were measured
up to a spin I = 16+ by a transient magnetic field-ion implanted perturbed angular distribution method and
calculated by a cranking shell model. A peak structure of the g-factors has been observed for the first time. The
measured g-factors confirm the mixed configuration of proton and neutron alignments.
