Effect of pressure on the ferroquadrupolar compound TmAu 2
Abstract
TmAu 2 with a simple body-centered tetragonal MoSi 2-type structure undergoes an electric transition to a ferroquadrupolar ordered state at TQ of 7.0 K and a magnetic transition to an antiferomagnetic state at TN of 3.2 K. We have measured pressure dependence of electrical resistivity on single-crystalline TmAu 2 sample. The results reveal that the TN decreased with increasing pressure (∂ TN/∂ P=-4.54 mK/kbar), while the TQ increased with increasing pressure (∂ TQ/∂ P=21.5 mK/kbar).
