WebSep 15, 1991 · The usual finite-size scaling is generalized by including n/Ξ s as an additional scaling variable, with n the number of layers. The bulk transition temperature is governed by a new scaling function F s (n/Ξ s), which decreases with n for n < Ξ s, but increases with n for n >Ξ s. Qualitative trends agree well with the experiments.
