Abstract

The trigonal-to-pseudotetragonal structural first-order transition in [111]-stressed SrTiO3, realizing the three-state Potts model, is studied in the close vicinity of the bicritical point (BCP). The exponents describing the effects of fluctuations on this transition are shown to cross over from XY- to Gaussian-model values as the BCP is approached. The first-order line is shown to approach the BCP tangentially to the temperature axis.
