We report experimental studies on a series ofRb(Co$_{1-x}$Ni$_{x}$)$_{2}$Se$_{2}$ (0.02 $\leq x \leq $ 0.9) powder andsingle crystal samples using x-ray diffraction, neutron diffraction, magneticsusceptibility, and electronic transport measurements. All compositions aremetallic and adopt the body-centered tetragonal structure with $I4/mmm$ spacegroup. Anisotropic magnetic susceptibilities measured on single crystal samplessuggest that Rb(Co$_{1-x}$Ni$_{x}$)$_{2}$Se$_{2}$ undergo an evolution fromferromagnetism to antiferromagnetism, and finally to paramagnetism withincreasing Ni concentration. Neutron diffraction measurements on the sampleswith $x$ = 0.1, 0.4, and 0.6 reveal an $A$-type antiferromagnetic order withmoments lying in the $ab$ plane. The moment size changes from 0.69 ($x=0.1$) to2.80$\mu_B$ ($x=0.6$) per Co ions. Our results demonstrate that dilution of themagnetic Co ions by substitution of nonmagnetic Ni ions induces magneticlocalization and evolution from itinerant to localized magnetism inRb(Co$_{1-x}$Ni$_{x}$)$_{2}$Se$_{2}$.
