| Abstract: | The magnetic susceptibility of the ternary compounds, RPd2Si2 (where R=Gd, Tb, Dy, Ho and Er) has been measured. GdPd2Si2 order antiferromagnetically at 13 and 20 K respectively; the rest of the compounds do not show clear ordering down to 4.2 K. Palladium carries no moment in these compounds. The De Gennes formula is not obeyed indicating that the exchange interaction between the 4f moments via conduction electrons is not isotropic |
