Indirect exchange ordering

In order to succeed with this mechanism, it will be necessary to prepare compounds with a better overlap of the involved orbitals to get an effective indirect exchange mechanism.

The RPds compounds, as seen in fig. 14.56 are different from the other RB3 compounds in that the ordering temperatures are either extremely low or non-existent (Gardner et al., 1972). This can be understood partly if one considers that Pd has a tendency to fill its 4d-shell. This is the case even in dilute alloys of rare earths dissolved in Pd, which are not discussed here. A Pd ion with a full 4d-shell then contributes no electrons to the conduction band and indirect exchange via the...
