Pulsed-magnetic-field measurements of Hall potential oscillations in alpha-(BEDT-TTF)(2)TlHg(SCN)(4) within the quantum Hall regime

Pulsed-magnetic-field measurements of Hall potential oscillations in alpha-(BEDT-TTF)(2)TlHg(SCN)(4) within the quantum Hall regime

Using a variant of the Corbino geometry in pulsed magnetic fields of up to 60 T, we have made direct measurements of the Hall potential in α-(BEDT-TTF)2TIHg(SCN)4 within the quantum Hall regime. This method enables the in-plane components of the resistivity tensor, which are normally very difficult...

Summary:Using a variant of the Corbino geometry in pulsed magnetic fields of up to 60 T, we have made direct measurements of the Hall potential in α-(BEDT-TTF)2TIHg(SCN)4 within the quantum Hall regime. This method enables the in-plane components of the resistivity tensor, which are normally very difficult to measure, to be investigated and the nonlinear behavior of the sample's I-V characteristics to be studied. It is found that an increasing probability of magnetic breakdown at higher fields leads to a degradation of the quantum Hall effect. ©1999 The American Physical Society.
