摘要：

The physical properties of YbBiPt are complicated because there are three competing energy scales all of order 1 K: the coupling energy between Yb moments as measured by the Neel temperature (T(N)), the splitting between the groundstate and first excited crystal electric field levels (T(DELTACEF)) and the Kondo temperature (T(K)). The magnetically ordered phase below T(N) = 0.45 K appears to be reduced local moment ordering that is incommensurate with the lattice. Associated with this order is the formation of a superzone gap that can be detected by electrical resistivity measurements. Attempts to treat T(K) and T(DELTACEF) separately only account for gross features of the data presented.
