In the composite fermion model of the fractional quantum Hall effect,
composite fermions experience, in addition to the usual potential diso
rder, also a magnetic flux disorder. Motivated by this, we investigate
the localization properties of a single fermion in two dimensions, mo
ving in the presence of both static potential and static magnetic flux
disorders, but with a non-zero average magnetic field. It is found th
at the exponent characterizing the divergence of the localization leng
th is not changed upon the addition of the flux disorder, provided it
is not too large.
