Abstract

A simple molecular field model is presented for the prediction of magnetic transition temperatures of rare-earth (RE) compounds when crystalline electric field (CEF) splittings are significant. The model is applied to the RERh4B4 (RE=GdTm) series, using what is known about the crystal field in these materials.

    The theoretical dependence is almost fulfilled for the paramagnetic Curie temperatures while for the critical temperatures of magnetic ordering (TC,N) a large discrepancy between the experimental and calculated temperatures is observed, especially visible for R = Tb and Dy. Such a result indicates a strong influence of crystalline electric field (CEF) on stability of the magnetic order [27]. Similar discrepancies have been observed in R2CoIn8 [17] and R2CoGa8 [28] (R = rare earth element).

    This result is in agreement with the large R-R interatomic distances and metallic character of the temperature dependence of the electrical resistivity [21]. Noticeable discrepancy between the experimental and theoretical values of TN for Tb2TGe6 (T = Ni, Pd) can be attributed to the influence of the crystalline electric field [26]. The role of the CEF manifests itself also in a reduction of the magnetic moments in the ordered state in comparison to the free R3+ ion values (see Table 2).
