摘要：
Angular dependent magnetotransport measurements on the fractional quantum Hall (FQHE) states around Landau level filling factor v = 3/2 are explained very effectively in terms of composite fermions (CFs) with a spin. The disappearance and reappearance of FQHE states as well as their spin polarization is deduced from a simple ''Landau level'' fan diagram for CFs. While the ''Landau splitting'' scales with effective magnetic field, with its origin at v = 3/2 the spin-splitting scales with total external magnetic field having Its origin at B = 0. The g factor of a CF is largely the g factor of the electron.
