Abstract

Two charge density wave transition can be detected in LaAuSb2 at similar to 110 and similar to 90K by careful electrical transport measurements. Whereas control of the Au site occupancy in LaAuxSb2 (for 0.9 less than or similar to x less than or similar to 1.0) can suppress each of these transitions by similar to 80K, the application of hydrostatic pressure can completely suppress the lower transition by similar to 7.5kbar and the upper transition by similar to 17kbar. Clear anomalies in the resistance as well as the magnetoresistance are observed to coincide with the pressures at which the charge density wave transitions are driven to zero.
