  The structural characterization and electrical transport measurements at
ambient and applied pressures of the compounds of the La(Ag1-xAux)Sb2 family
are presented. Up to two charge density wave (CDW) transitions could be
detected upon cooling from room temperature and an equivalence of the effects
of chemical and physical pressure on the CDW ordering temperatures was observed
with the unit cell volume being a salient structural parameter. As such
La(Ag1-xAux)Sb2 is a rare example of a non-cubic system that exhibits good
agreement between the effects of applied, physical, pressure and changes in
unit cell volume from steric changes induced by isovalent substitution.
Additionally, for La(Ag0.54Au0.46)Sb2 anomalies in low temperature electrical
transport were observed in the pressure range where the lower charge density
wave is completely suppressed.
