Abstract

Measurements of the hydrostatic pressure dependence of the Neél temperatures, TN, are reported for PrSn3, GdSn3, GdSn3 and CeIn3. TN is found to increase with applied pressure for PrSn3 and NdSn3, whereas TN is pressure independent within experimental error for GdSn3 and CeIn3. Slightly Sn-deficient RESn3 (RE=rare earth) compounds are found consistently to be weakly ferromagnetic. The physical properties of the RESn3 compounds exhibit analogies with the corresponding properties of dilute superconducting (LaRE)Sn3 alloys. The high pressure data for PrSn3 and CeIn3 are qualitatively consistent with a "Kondo necklace" model for magnetically ordered RE compounds with unstable 4f shells.
