In this paper, the temperature dependence of differential magnetoresistance oscillations in a heterostructure based on an In₀.₅₃Ga₀.₄₇As quantum well is studied. The analysis was carried out in weak (0.6–1.22 T) and strong (up to 4 T) magnetic fields, over a temperature range of 3–40 K. While no oscillations are observed in ordinary magnetoresistance in weak fields, oscillations related to Landau levels appear when the differential magnetoresistance (dρ/dB) is calculated. As the temperature increases, the amplitude of the oscillations decreases. The differential method enables visual observation of Landau quantization even in weak magnetic fields.
