| dc.description | The pressure dependence of the Curie temperature (T<sub>c</sub>) was determined up to 40 kbar for the compounds R<sub>2</sub>Co<sub>17</sub> (R=Nd, Gd, Er, Y and Th), RCo<sub>5</sub> (R=Gd, Y and Th), R<sub>2</sub>Co<sub>7</sub> (R=Gd and Y), RCo<sub>3</sub> (Gd, Y and Pr) and RCo<sub>2</sub> (R=Gd and Tb). Single phase compounds with off-stoichiometric composition were included in this investigation. The experimental data are discussed in terms of the collective electron model. With few exceptions the pressure derivative of T<sub>c</sub> of the various compounds can be represented by a general relation of the form dT<sub>c</sub>/dP=<sup>5</sup>/<sub>3</sub> kappa T<sub>c</sub>-<sup>5</sup>/<sub>6</sub> kappa B/T<sub>c</sub> with B=3.5*10<sup>6</sup>K<sup>2</sup> and T<sub>c</sub> ranging from 400-1200K. For the compounds Y<sub>2</sub>Co<sub>17</sub>, YCo<sub>5</sub>, YCo<sub>3</sub>, YCo<sub>2</sub>, GdCo<sub>5</sub>, ThCo<sub>5</sub> and Th<sub>2</sub>Co<sub>17</sub> the compressibility kappa was determined. |
