We propose an experiment to identify the potential existence of a spinon Fermi surface by looking for oscillatory coupling between two ferromagnets via a spin liquid spacer. Three candidate spin liquids are investigated, and it is found out that in all cases long period oscillations should be present, the period of which would identify the Fermi wave vector of the spinon surface.
我们提出了一个实验,通过一个自旋液体间隔层寻找两个铁磁体之间的振荡耦合,以确定自旋子费米面的潜在存在。我们研究了三种候选自旋液体,发现所有情况下都应存在长周期振荡,其周期将确定自旋子表面的费米波矢。
