(0≤x≤1) by pressure.*

LaAgSb₂ exhibits two CDW transitions at ambient pressure: at T₁ ~ 207 K a lattice modulation along the a-axis develops and upon further cooling, at T₂ ~ 186 K, an additional CDW ordering along the c-direction appears. [1] Here, we report resistivity measurements on La(Ag_1-xAu_x)Sb₂ (0≤x≤1) samples at ambient and high pressure that reveal suppression of both CDW transitions by pressure and Au substitution. By introducing simple pressure scale shifts for different x-values, the T(P) data fall onto universal T₁(P*) and T₂(P*) curves. Results will be compared with and contrasted to the literature data on (La_1-xR_x)AgSb₂ (R = Ce, Nd). [2]
