Pressure dependence of the charge-density-wave and superconducting states in GdTe${}_3$, TbTe${}_3$ and DyTe${}_3$

Abstract

We present electrical resistivity and ac-susceptibility measurements of GdTe${}_3$, TbTe${}_3$ and DyTe${}_3$ performed under pressure. An upper charge-density-wave (CDW) is suppressed at a rate of $\mathrm{d}{T}_{\mathrm{CDW},1}/\mathrm{d}P$ = $-$85 K/GPa. For TbTe${}_3$ and DyTe${}_3$, a second CDW below $T_{\mathrm{CDW},2}$ increases with pressure until it reaches the $T_{\mathrm{CDW},1}$($P$) line. For GdTe${}_3$, the lower CDW emerges as pressure is increased above $\sim$ 1 GPa. As these two CDW states are suppressed with pressure, superconductivity (SC) appears in the three compounds at lower temperatures. Ac-susceptibility experiments performed on TbTe${}_3$ provide compelling evidence for bulk SC in the low-pressure region of the phase diagram. We provide measurements of superconducting critical fields and discuss the origin of a high-pressure superconducting phase occurring above 5 GPa.
