Abstract
The experimental critical behavior of the susceptibility of Li is described by the power law with K and . This behavior is dramatically different from that previously observed in LiTb and is evidence of a departure from marginal dimensionality when magnetic ions have been randomly replaced by nonmagnetic ions. Series expansion of in powers of for a diluted Ising dipolar ferromagnet gives a good description of experimental results described in this Letter.
