“…Although Rb 2 ZnCl 4 was considered to belong to the 3D-XY universality class in[33], these critical exponents are closer to the recent 3D Ising values[1]. The critical exponent ¼ 1.228 AE 0.014 for YIG (Y 3 Fe 5 O 12 )[35] is closer to the 3D Ising value ¼ 5/4[1] than to the mean field value ¼ 1 or the Heisenberg value ¼ 4/3. The critical exponent ¼ 0.365 AE 0.015 was obtained for NiCO3 …”

“…Second, continuous symmetry applies not only asymptotically for T-T c but sets in at a well-defined crossover temperature above the critical point [12]. This is approximately at the change from Curie-Weiss susceptibility to critical susceptibility.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
