Two charge density wave transition can be detected in at and by careful electrical transport measurements. Whereas control of the Au site occupancy in (for ) can suppress each of these transitions by , the application of hydrostatic pressure can completely suppress the lower transition by and the upper transition by . Here, 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.
