The two-dimensional hole gas (2DHG) magnetoresistivity of a Si0:7Ge0:3=Si0:2Ge0:8 heterostructure in a wide range of temperatures T = 0:335-20 K and transport currents I = 100-50 A is measured. In the vicinity of zero magnetic ÿeld, a sharp and positive in sign feature on smooth negative magnetoresi
