摘要：

A specific microstructural model involving short- or long-range order of (Ba,Sr)[La] dopant substituents explains the composition x0 = 0.125 most favorable for the formation of the low-temperature Ba[La] tetragonal phase. The microstructural model shows that the normal state of these alloys can be described as a two-component Fermi liquid in order to explain the acoustic, magnetic, and thermal anomalies centered on x0 as well as the related drastic reduction in T(c) over a narrow range of x.
