  We report magnetotransport measurements in a HgTe quantum well with an
inverted band structure, which is expected to be a two-dimensional (2D)
topological insulator. A small magnetic field perpendicular the 2D layer breaks
the time reversal symmetry and thereby, suppresses the edge state transport. A
linear magnetoresistance is observed in low magnetic fields, when the chemical
potential moves through the the bulk gap. That magnetoresistance is well
described by numerical calculations of the edge states magnetotransport in the
presence of nonmagnetic disorder. With magnetic field increasing the
resistance, measured both in the local and nonlocal configurations first
sharply decreases and then increases again in disagreement with the existing
theories.
