Abstract

We have observed features in the magnetoresistance of a wide
parabolic quantum well in the presence of the in-plane magnetic
field at field three times larger than fundamental field
corresponding to the depopulation of the last Landau level. The
magnetoresistance structures shift with a specific sample
parameter, such as potential width. We suggested the formation
of correlated states of a three-dimensional electron gas at
Landau filling factor 1/3, in analogy with a two-dimensional
fractional quantum Hall effect.
