The low field temperature dependence of the magnetization of some RCu2 (R=Dy, Ho, Er)
compounds has been measured under hydrostatic pressures up to 5 kbar. Apart from the antiferromagneticparamagnetic
transitions additional transitions have been observed for HoCu2 and ErCu2 below their N??el
temperatures. For the DyxY1-xCu2 compounds the dependence of the N??el temperature on the Y content
has been determined. The results are discussed in the RKKY model. ?? 1983.
