摘要：
We present measurements of the real diagonal microwave conductivity of the reentrant insulating quantum Hall phases in the first excited Landau level at temperatures below 50 mK. A resonance is detected around filling factor nu=2.58 and weaker frequency dependence is seen at nu=2.42 and 2.28. These measurements are consistent with the formation of a bubble phase crystal centered around these v at very low temperatures.
