Low-temperature dependences of the amplitude of magneto-intersubband resistance oscillations (\(\Delta {{R}_{{{\text{MISO}}}}}\)) on the magnetic field \(B < 2\) T are studied in single GaAs quantum wells with the width (\({{d}_{{{\text{SQW}}}}}\)) from 22 to 46 nm and two occupied quantum confinement subbands \({{E}_{1}}\) and \({{E}_{2}}\). It is established that additional damping appears in dependences of \(\Delta {{R}_{{{\text{MISO}}}}}\) on 1/\(B\) in the studied quantum wells, which is explained by the effect of large-scale fluctuations of the intersubband splitting \({{\Delta }_{{12}}} = {{E}_{2}} - {{E}_{1}}\) on the amplitude of oscillations \(\Delta {{R}_{{{\text{MISO}}}}}\). It is found that the suppression of oscillations \(\Delta {{R}_{{{\text{MISO}}}}}\) with the increase in 1/\(B\) is more efficient in “narrow” quantum wells. This experimental fact makes it possible to suppose that the main origin of fluctuations of \({{\Delta }_{{12}}}\) in the studied narrow quantum wells is large-scale fluctuations of the well width \({{d}_{{{\text{SQW}}}}}\). An expression taking into account the role of large-scale fluctuations of \({{\Delta }_{{12}}}\) in the damping of \(\Delta {{R}_{{{\text{MISO}}}}}\) is obtained. The comparison of theory and experiment has made it possible to determine the average amplitude of fluctuations of the intersubband splitting in the studied GaAs quantum wells.
