We have used x-ray resonant magnetic scattering at the Tb L-2 edge to elucidate the nature of magnetic ordering in Cd6Tb, a 1/1 approximant closely related to the Cd-Mg-R ( R = rare earth) icosahedral alloys. Below T-N approximate to 24 K, the ordered moments associated with the icosahedral clusters at the corners and body center of the pseudocubic unit cell are antiferromagnetically correlated, and long-range magnetic order is realized.
