The asymptotic critical behavior of the coarse-grained polycrystalline sample (with an average crystallite size of $L \\cong \\unit[100]{\\mu m}$) is that of a (pure) \\textsl{uniaxial dipolar} ferromagnet, as is the case with single-crystal Gd, albeit the width of the asymptotic critical region (ACR) is reduced. As the grain size approaches $\\sim \\unit[30]{nm}$, the ACR is so narrow that it could not be accessed in the present experiments.
