Figure 3From: Direct measurement of the spin gaps in a gated GaAs two-dimensional electron gasLogarithm of the amplitudes of the oscillations. The logarithm of the amplitudes of the oscillations divided by T ln(Δρxx / T) as a function of temperature at different magnetic field for sample C at Vg = 0. The curves correspond to fits described by [18]. The inset shows the measured effective mass at different magnetic fields.Back to article page
