Modulation effect of transverse currents on the switch and hysteresis characteristics in blue bronze Rb0.3MoO3

The modulation effect of transverse current on the switching with hysteresis characteristics of quasi-1D charge-density wave conductor rubidium blue bronze Rb0.3MoO3 single crystals was investigated for the first time. The behavior of the transverse current dependence of second threshold field E T 2 ( E – I characteristic curves) was obtained at 24 K under the current source driving. The E T 2 gradually decreases with the increase of transverse current I T when transverse current I T exceeds a certain value I C . The E – I curves become smoother and the switching shows a gentle weakening by the increasing of I T . Correspondingly, the I – E properties (voltage source driving) with an obvious switching from a low conducting state to a high conducting state were measured under the modulation of transverse current. Gradually, the E T 2 cannot be distinguished with transverse current increase. The areas of the hysteresis characteristics loop become gently smaller when transverse current increases. It is noted that the transverse currents only induce E T 2 to decrease when they go up, yet however, hardly affect the back curves of the hysteresis loop. This could explain the effect of the transverse current as not a thermal effect, because the back curves of the hysteresis loop are not identical at different temperatures.
