Figure 6
Measured \(R_{xy}/R_{K}\) values at the diagonal resistance minima versus cos(\(\theta\)) in Hall bars with \(W = 400, 200,\) and \(100\, \mu m\). (a) and (b) illustrate the observed \(R_{xy}/R_{K}\) versus cos(\(\theta\)), where \(\theta\) is the tilt angle, at the corresponding \(R_{xx}\) minima for the sample widths of 400, 200, and 100 micrometers. The dotted lines indicate the expected \(R_{xy}/R_{K}\) values at the well known fractional states labeled on the right ordinate. Note that, at \(\nu =p/q\) , where p/q is a rational fraction, one expects Hall resistance \(R_{xy}/R_{K} = (p/q)^{-1}\).
