Logarithmic temperature dependence of conductance G(e2/h) in different magnetic fields measured for CBS films with different thicknesses when the PMN-PT substrates are in the \(P_r^ +\) and \(P_r^ -\) states, respectively. The black solid lines are linear fitting results obtained with Eq. (1). Lower panels of a–d show the magnetic field dependence of the coefficient K extracted from Eq. (1) for both polarization states of PMN-PT, respectively
