论文摘要
通过仔细的电气传输测量值，可以在LAAU $ _X $ _x $ _2 $ _2 $ _2 $ _2 $ _2 $中检测到两个电荷密度波转换。虽然控制laau $ _x $ sb $ _2 $（0.9 <x <1.0）的AU站点占用率可以抑制这些过渡中的每一个，但静水压力的应用可以完全抑制〜10 kbar的下部过渡，而上过渡则降低了〜17 kbar。观察到电阻的清晰异常以及磁磁性与电荷密度波变变驱动到零的压力相吻合。
Two charge density wave transition can be detected in LaAu$_x$Sb$_2$ at ~ 110 and ~ 90 K by careful electrical transport measurements. Whereas control of the Au site occupancy in LaAu$_x$Sb$_2$ (for 0.9 < x < 1.0) can suppress each of these transitions by ~ 80 K, the application of hydrostatic pressure can completely suppress the lower transition by ~ 10 kbar and the upper transition by ~ 17 kbar. 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.
