Anisotropic nematic fluctuations above the ferroquadrupolar transition in TmVO${}_4$

Z. Wang, I. Vinograd, Z. Mei +5

TmVO${}_4$ exhibits ferroquadrupolar order below 2.15 K with a well-isolated non-Kramers ground state doublet, and is a model system to understand Ising nematic order. We present $^{…
