AB - <p>The pressure dependence of the superconducting transition temperature's, T<sub>c</sub>, of fourteen samples in the pseudoternary system (Th<sub>1-x</sub>Y<sub>x</sub>)Rh<sub>4</sub>B<sub>4</sub>&nbsp;are reported for hydrostatic pressures up to 21 kbar. The Y rich samples show an enhancement of T<sub>c</sub> with applied pressure, whereas for the Th rich compounds T<sub>c</sub> is depressed by pressure. A broad plateau in dT<sub>c</sub>/dp as a function of x is observed for nearly equiatomic (0.4 &lt;= x &lt;= 0.80) compositions. The non-linear behavior of T<sub>c</sub> as a function of pressure for the Y rich samples (x &gt; 0.80) is discussed with reference to prior measurements on YRh<sub>4</sub>B<sub>4</sub>. Observation of this non-linearity may be related to the purity of the Y source material or the presence of a pressure-induced phase transformation. (12 References).</p>
