Abstract

Detecting the zero-temperature thermal Order-by-Disorder transition in classical magnetic systems is notably difficult. We propose a method to probe this transition in an indirect way. The idea is to apply adequate magnetic fields to transform the zero temperature transition into a finite temperature sharp crossover, which should be much easier to observe and characterise with usual laboratory methods.
