Abstract

Magnetodrag reveals the nature of compressible states and the underlying interplay of disorder and interactions. At ν=3/2 clear T4/3 dependence is observed, which signifies the metallic nature of the N=0 Landau level. In contrast, drag in higher Landau levels reveals an additional contribution, which anomalously grows with decreasing T before turning to zero following a thermal activation law. ...
