Abstract
The planar Heisenberg system with antiferroquadrupolar exchange on a three-dimensional stacked triangular lattice is shown to belong to the "chiral" universality class, predicted for chiral antiferromagnets. The present system, however, displays no such chirality, which, according to the current widely accepted concept, is supposed to be a key ingredient for the nonstandard (chiral) critical behavior. Our claim that the chiral universality classshould not be limited only to chiral antiferromagnets is based on a simplemapping between the chiral antiferromagnetic and antiferroquadrupolar systems and supported by actual calculations of the transition temperatures andcritical indices from finite-size scaling analysis of data issued from histogram Monte Carlo simulations. In order to demonstrate the existence of two different universality classes in the behavior of quadrupolar systems, finite-size scaling is also performed for the system with ferroquadrupolar exchange, which, in contrast to the antiferroquadrupolar exchange system case, produced standard critical behavior, as could also be anticipated from the mapping.
