TmAu2 with a simple body-centered tetragonal MoSi2-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 TmAu2 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).
