Detecting the zero-temperature thermal order-by-disorder (ObD) 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 and suitably engineered 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. Such a crossover should constitute proof of existence of the ObD transition in the underlying unperturbed system.

检测经典磁性系统中的零温度热按序（ObD）跃迁非常困难。我们提出了一种间接探测这种转变的方法。这个想法是要施加足够的，经过适当设计的磁场，以将零温度转变转变为有限温度的尖峰交叉，这应该更容易用常规实验室方法观察和表征。这样的交叉应该证明在底层不受干扰的系统中存在ObD过渡。
