Abstract
In the framework of an extended phenomenological approach to phase transitions, it is shown that existing nonlinear relation between local critical atomic parameters and phenomenological order parameter induces the corresponding nonlinear temperature scaling transformation. An explicit form of such a transformation was found. Theoretically predicted uniform function reproduces well the experimentally observed behavior of order parameters in different systems.
